开封市祥符区盐碱地治理方案探析

Analysis on Saline-alkali Treatment Scheme in Xiangfu District of Kaifeng City

开封市祥符区由于地下水位偏高和地下水排泄不畅,造成大面积的土壤盐碱化,针对盐碱化存在现状进行调查分析。以杜良乡为例,分析杜良盐渍化形成的自然因素和人为因素。从而提出:以水利明沟排水为主,农业改良措施以及生物改良措施为辅的综合治理方案,并对排水系统进行了设计,明确了生物、化学改良的具体措施。可对开封市祥符区的盐碱地治理起到示范带动作用。

Xiangfu district in Kaifeng is located in the high groundwater level and poor drainage of groundwater, results in a large area of soil salinization. The presence of salinization status is investiged and analyzed. Taking Du Liangxiang as an example, the natural factors and human factors of salinization of Du Liang were analyzed. This paper puts forward the comprehensive management plan of water conservancy ditch drainage, agricultural improvement measures and biological improvement measures, and designs the drainage system, and clarifies the specific measures of biological and chemical improvement. Can be Kaifeng City Xiangfu District of salt and alkali control play a leading role in the demonstration.
