"This 10, 000 acres of ecological anti-pollution forest to go down, xikuangshan ecological debt will return a large sum!"A few days ago, lengshuijiang city forestry department and provincial academy of forestry experts came to the xikuangshan area, to the anti-pollution forest area has been planned for the final confirmation.Lengshuijiang city decided to use the winter and spring afforestation season in xikuang area to plant another 10,000 mu of ecological anti-pollution forest.

Tin mine is the world famous 100 years old mine, the cumulative production of antimony about 1/4 of the world.While contributing to economic development, the century-long mining has also paid a heavy price for the destruction of the ecological environment.How to repay the ecological debt, lengshuijiang city proposed to build a two-type social demonstration zone in xikuang district, and implemented 38 heavy metal pollution control projects.On the one hand, comprehensive management and dynamic supervision should be carried out on the waste residue, and large arsenic-alkali residue Banks should be built and waste residue accumulation sites should be planned to prevent random stacking and leakage from causing secondary pollution.On the other hand, comprehensive treatment should be carried out to construct a harmless treatment project with an annual treatment capacity of 20,000 tons.Within seven years, it is expected to be fully digested.

At the same time, full implementation of tin mine ecological restoration project, the establishment of ecological anti-pollution, ecological restoration research base.Tree species suitable for growth in heavy metal superstandard soil, such as brassica, privet, catalpa, etc., were selected to construct ecological anti-pollution forest.This winter and next spring, a new anti-pollution forest of 10, 000 mu will be built in xikuangshan area by cold-water river. At that time, the forest coverage rate in the rocky desertification area will reach 100%.From January to July this year, the average daily concentration of sulfur dioxide monitored by the ambient air in xikuangshan dropped by 76.7% year on year.The mean values of arsenic and antimony in qingfenghe river decreased by 73.17% and 26.84% respectively, while those in lianxi river decreased by 85.48% and 47.75% respectively.The governance results have been highly affirmed by the provincial government.
