Novel method applicable to treatment of seasonal waterlogged coal-mining subsidence land
The invention discloses a novel method applicable to treatment of a seasonal waterlogged coal-mining subsidence land. The method is characterized in that a water collection control project is utilized for comprehensively balancing the water and soil resources in a subsidence area, so as to solve the problem that unsmooth draining in the subsidence land leads to decrease of the quality of cultivated lands; the subsidence land is reconstructed into a quality land capable of draining in case of flooding and irrigating in case of drought. The method has the advantages that 1, a plurality of dispersed water collection pits/ ponds are constructed to achieve the space regulation of the water resources as well as improving the irrigating and flood draining support capacity; 2, the water in the dispersedly constructed pits/ ponds is able to improve the biodiversity of the treatment area; 3, the pits/ ponds construction solves the problem of the earth resources in land reclamation of a bottomland in the subsidence area.
