The soil environmental quality of cultivated land in Hechi City is not optimistic as a whole. Soil pollution is serious, and a considerable part of cultivated land is seriously polluted, which affects the production and safety of agricultural products. In 2013, the Environmental Planning Institute of the Ministry of environmental protection of the people's Republic of China carried out monitoring and investigation on the soil environmental quality of Hechi. A total of 603 soil sampling points were set up, and 197 samples exceeded the standard, accounting for 32.67%. About one third of the soil monitoring points exceeded the standard, mainly in Nandan county, Jinchengjiang District, Huanjiang County and Luocheng County, accounting for 22.84%, 20.81%, 19.29% and 19.29%, respectively 13.71%。 Representative he Xinxing said that in terms of the excessive amount of heavy metals in the soil, cadmium was the most serious, accounting for 84.77% of the total number of over standard points, followed by arsenic, mercury, lead and chromium. The monitoring results show that the heavy metal pollution of cultivated soil in Hechi City is serious, and it is urgent to carry out treatment and remediation. With the strong support of the state and Guangxi Zhuang Autonomous Region, in recent years, Hechi has implemented a number of environmental treatment projects, and carried out the preliminary work of remediation of heavy metal contaminated farmland. In particular, since the launch of the "beautiful Guangxi · clean countryside" activity, Hechi has actively carried out the "clean countryside" activity, pushing forward ten major projects and ten main technologies of the "clean countryside" activity, with a total area of 3095500 mu, accounting for 55.14% of the total cultivated land area. He Xinxing said that although the work of harnessing farmland polluted by heavy metals in Hechi has achieved positive results, the task is still very arduous, and it is difficult to complete the task only by ourselves. This year, the state will launch a Heavy Metal Contaminated Farmland treatment project. It is suggested that the state should support Hechi City in the implementation of Heavy Metal Contaminated Farmland remediation project, and give preferential support to policies, projects and funds. In the project, a large number of composite geomembrane produced by Xinyu engineering environmental protection Co., Ltd!
