- The Land Degradation and Preventing and Curing Countermeasures in Hangjin County of Inner Mongolia Autonomous Region
- Keywords:
- Hangjin county; land degradation; ecology harnessing
- 摘要:
- 杭锦旗地处黄河南岸、鄂尔多斯高原西北部，属典型的生态环境脆弱区，因自然和人为因素的不良影响，使土地大面积退化。退化类型多样，有风蚀沙化、草地退化、水土流失和土壤次生盐渍化等，其中以风蚀沙化和草地退化为主。治理措施的重点是进一步调整土地利用结构，建立生态经济型土地利用结构，并根据用地方向和治理重点进行分区治理。切实保护耕地，并大力营造生态林草，防风固沙，水土保持；加强草原建设，以草定畜，恢复和提高草地生产力，使草地得到永续利用。
- Abstract:
- Hang im county lies in the south bank of the Yellow River, northwest of the Eerduosi plateau. It is the typical ecological environment weak region,because of the bad effect ofthe natural and human elements, the land was degradated in large area. The degradation wasoccured in different degree in almost all over the county. The type of the degradation was various, such as, the wind eroded sandification, the grassland degradation, loss of soil and watererosion and the soil secondary salinization. Among these, the wind eroded sandificatlon and thegrassland degradation were major. The important point of the harnessing methord was deep adjusted the land use structure, set up the land use structure of the ecologic economic types, andon the basis of the land use direction and the important point of the harnessing, to divid area toharness. Make sure to protect the farmland make efforts to plant ecologic forest and grass,prevent wind and regularize sand,conserve water and soil. Strengthen the grassland construction, determine the qtlantity of the animal based on the grasslalld production,restore and raisethe grassland productive forces, make the grassland can be sustaining used.
