三江平原低湿地 ,土壤粘重 ,释水能力差 ;一遇暴雨积水迅速汇入低平原 ,由于平原内河网密度小 ,安全泻洪排涝能力低 ,造成了洪涝渍灾害。要改变土壤释水能力或短时间排走积水径流 ,都需要巨在原投资和时间 ,并且在解决排水后 ,依然存在干旱问题。经多年试验调查研究 ,建立了“排 ,蓄 ,用”相结合的水利工程治理模式。这种工程模式能够使开发小区在较小的投入情况下 ,使水土资源趋利避害 ,因势利导 ,变单一低产种植业 ,成为农、林、牧、鱼业综合性经济区。这样不但最大限度地发挥当地水土资源优势 ,而且使动植物以及人类赖以生存的自然环境向良性型方向发展 Sanjiang Plain, low wetlands, the soil sticky, poor water release capacity; a case of storm water quickly into the low plain, due to the plains inland river density is small, safe flood waterlogging drainage capacity is low, resulting in flood disaster. To change the ability of soil to release water or discharge runoff for a short period of time requires enormous investment and time, and after the drainage problem is solved, the drought problem still exists. After many years of experimental investigation and research, the establishment of “row, storage, with” a combination of water conservancy project management model. This project mode enables the development community to make the water and soil resources benefit and avoid disadvantages under the condition of small input, and make the production of monoculture and low-yield planting industry become the comprehensive economic zone of agriculture, forestry, animal husbandry and fishery. This will not only give full play to the advantages of local water and soil resources, but also make the natural environment on which animals, plants and humans depend for survival will grow benignly
