Abstract: The emergence of vegetable greenhouses greatly improves the yield and diversity of vegetable crops, but has a negative impact on the soil. This paper briefly introduced the vegetable greenhouse and the methods used for evaluating the soil ecological risk and took a vegetable planting base in Yichang City of Hubei Province as the subject to carry out the soil pollution management and ecological risk analysis in the greenhouse planting area. The results showed that the content of heavy metals in the soil and the ecological risk increased with the continuous use of the greenhouse; after using organic fertiliser instead of chemical fertiliser, the content of heavy metals in the soil of both open-air farmland and greenhouse farmland were reduced, especially in the greenhouse farmland, in which the ecological risk was also reduced. Then, according to the test items and results, several suggestions were put forward for the soil pollution management of greenhouse vegetable planting.
