Title: Spatial balance degree evaluation model of land use based on regional collaborative remote sensing observation
Abstract:
In order to overcome the low accuracy of the traditional spatial balance evaluation method for land use, this paper constructs a spatial balance evaluation model for land use based on regional collaborative remote sensing observation. The land use information is collected by regional collaborative remote sensing observation system, and the evaluation index system and balance degree evaluation model are constructed by synthesising the information. The supply capacity index and the spatial development intensity index in the evaluation model are calculated by the arithmetic average method and the geometric average method. The ratio between them is defined as the output of the model. The experimental results show that the accuracy of this method is always over 95%, and the evaluation time is less than 2.1 s, which can realise the rapid and accurate evaluation of the spatial balance of land use.

Title: Dynamic prediction of urban landscape pattern based on remote sensing image fusion
Abstract:
In order to overcome the problems of large prediction error and slow prediction speed in dynamic prediction method of urban landscape, a new dynamic prediction method of urban landscape pattern based on remote sensing image fusion is proposed. The high-resolution remote sensing image is preprocessed by atmospheric correction and radiometric correction to obtain the fusion result of high-resolution remote sensing image. The urban landscape information is extracted from the fusion results, and the corresponding urban landscape pattern analysis model is built. The landscape pattern index is set up in the model, and the dynamic prediction of urban landscape pattern is completed by combining the characteristics of index change with the driving force and image factors of urban pattern change. The experimental results show that the average prediction error is 1.56, and the operation delay is reduced by 2 s-3 s.

Title: Research on dynamic simulation of land use change based on geographical weighted CLUE-S model
Abstract:
In order to overcome the problems of poor denoising effect, large quantitative accuracy error and large spatial accuracy error of current land use change simulation methods, a dynamic simulation method of land use change based on geographically weighted CLUE-S model was proposed. Using CLUE-S model to simulate the expansion of urban space, combined with geographic weighted logistic stepwise regression method, the influencing factors of land use change were analysed. The spatial distribution of future land use area is realised by iteration, and the spatial visualisation simulation of land use prediction is realised. The experimental results show that the signal-to-noise ratio of the proposed method is more than 85 dB, the quantitative and spatial accuracy errors are less than 4%, and the ROC value is close to 1, which proves that the spatial simulation effect is relatively good.

Title: Spatial-temporal evolution of complex urban landscape pattern based on remote sensing technology
Abstract:
In order to overcome the problem that the urban green landscape pattern construction effect is not ideal, this paper proposes the research method of spatio-temporal evolution of urban complex landscape pattern based on remote sensing technology. This method collects landscape pattern information. Landscape images are processed by radiometric correction and geometric correction, and spatial pattern indices are calculated. The experimental results show that: under the research method of spatiotemporal evolution of landscape pattern in this paper, the landscape area of dry land is reduced more, the transfer volume of residential, industrial and mining land and water area is less, and the stability is stronger. The density of landscape edge increased, indicating that the degree of landscape fragmentation in the city has a deepening trend. In terms of landscape spatial heterogeneity, the overall pattern tends to be coordinated, which indicates that the proposed method has good application performance.

Title: Dynamic remote sensing monitoring of land cover in ecological protection area based on GIS technology
Abstract:
In order to overcome the problems of large image deviation and unsatisfactory details retention in traditional monitoring methods, a new remote sensing dynamic monitoring research of land cover in ecological protection area based on GIS technology was proposed. In this method, the combination of joint entropy and optimal index is used to analyse and collect remote sensing images. The geometric distortion is corrected by using the binary homogeneous polynomial correction transformation formula. According to the image enhancement, the invalid information of the image is removed, and the land cover type change is described. Finally, the prediction of land cover dynamic change in the future is completed by creating Markov model. The experimental results show that the accuracy of the land cover remote sensing image data obtained is high, the land cover monitoring rate is 73%, the pixel accuracy is more than 90%, and the edge information maintenance advantage is significant.

Title: Reliability analysis of vacuum circuit breaker with permanent magnet material actuator based on competitive failure model
Abstract:
Of late, the permanent magnetic actuator has been used widely in the vacuum circuit breaker. The permanent magnet mechanism explored in this paper adopts the NdFeB permanent magnet. An important indicator of its reliability is the mechanical life of the vacuum circuit breakers (VCBs). In this study, 12 KV permanent magnet-operated VCBs have been tested for their mechanical fidelity. With the degradation failure following the Gaussian process and the traumatic failure of the Weibull distribution, the competition failure model has been established by considering the correlation between the two failure modes. The model parameter estimation was determined using the EM algorithm. Eventually, the reliability of the model was attained. This paper evaluates the results of different methods have been compared and analysed, which further proved that the method proposed in this paper had better evaluation accuracy and certain specific value for engineering application.

Title: Evaluation method and promotion countermeasures of green competitiveness for industrial enterprises under the background of environmental protection
Abstract:
Industrial enterprises are the foundation of the real economy and an important support for building strategic advantages for future development. The industrialisation process has created unprecedented material wealth for our country, but also produced irreparable environmental pollution. To comprehensively and objectively reflect the sustainable development ability of industrial enterprises, an evaluation method of green competitiveness for industrial enterprises is proposed. First, the construction principle of evaluation indices is put forward, and then the evaluation indices system of green competitiveness for industrial enterprises is constructed. In addition, in order to highlight the democratic characteristics of decision-making, an evaluation method of green competitiveness based on stakeholder perspective is proposed. Moreover, the green competitiveness of industrial enterprises in 14 cities is evaluated by using the evaluation method. Finally, the development countermeasures are put forward to promote the green competitiveness of industrial enterprises based on the evaluation results.

Title: The detection method for uneven settlement of foundation in the area of industrial waste miscellaneous filling
Abstract:
In order to overcome the problems of large error and long time in the detection process of traditional foundation subsidence detection methods, this paper proposes a multi-feature fusion based detection method for uneven foundation subsidence in the area of mixed industrial waste. The method USES wavelet transform technology to filter the ground image of the industrial waste filling area and improves the accuracy and timeliness of settlement detection fundamentally. After obtaining the optimal threshold values of different sub-blocks of the foundation image, combined with the multi-scale ridge edge fusion algorithm, the uneven settlement of the foundation area was detected by the feature fusion process. The experimental results show that the detection error of this method is basically kept below 4%, the detection process takes less than 50ms all the time, and the detection cost is less than 60,000 yuan, which fully demonstrates the effectiveness of this method.

Title: The purification mechanism of industrial wastewater by aquatic garden plants
Abstract:
In order to solve the current water pollution problem caused by industrial wastewater, the purification mechanism of aquatic garden plants on industrial wastewater is analysed and studied. The treatment process and influencing factors of plants in the purification process are analysed separately, and the purification mechanism of aquatic garden plants on different pollutant components in industrial wastewater is derived from a theoretical perspective. In order to verify the analysis results of the purification mechanism, the actual measurement analysis experiment of the purification effect of aquatic garden plants on industrial wastewater was designed. The experimental results show that aquatic garden plants can effectively reduce the content of TN, TP, COD, NH4+-N and heavy metals in industrial wastewater, and therefore have a high purification effect on industrial wastewater. Among a variety of aquatic garden plants, water onions and Canna's purifying effect is more obvious, and the removal rate can reach 83%.

Title: Study on plant landscape planning method based on discrete particle swarm optimisation
Abstract:
In order to solve the problems of low planning accuracy and high cost in traditional landscape plant landscape planning methods, a plant landscape planning method based on discrete particle swarm optimisation (DPSO) was proposed. The three-dimensional coordinate system of plant landscape planning path is transformed to determine the plant landscape planning path. The nonlinear programming mathematical model is used to constrain the plant landscape planning path, and the fitness objective function of plant landscape planning is obtained. The particle swarm optimisation algorithm is used to optimise the plant landscape planning path, and the particle swarm optimisation algorithm is used to improve the plant landscape planning path. The convergence was optimised to complete the plant landscape planning. The experimental results show that the accuracy of path planning is up to 98% and the aesthetic degree of plant landscape is more than 95%.

Title: A prediction model of shallow groundwater pollution based on deep convolution neural network
Abstract:
In order to solve the problems that the shallow groundwater pollution is affected by water quality in the prediction process, resulting in the low prediction index and water quality index of shallow groundwater pollution, a prediction model of shallow groundwater pollution based on deep convolution neural network is proposed. The index system of shallow groundwater pollution is constructed, and contents of dissolved oxygen, oxygen demand, ammonia nitrogen and pH in shallow groundwater are determined. With the help of gradient descent method and Guss-Newton method, the weight of index content is modified; the modified content value of pollution index is entered into the depth convolution neural network for optimisation, and the optimised value is obtained to complete the shallow groundwater pollution prediction model. The experimental results show that the maximum prediction index of shallow groundwater pollution is about 0.99, and the maximum value of water quality index is close to 1.
