摘要
在系统论述我国内陆盐碱化沼泽分布和特征基础上 ,分析了内陆盐碱化沼泽形成的环境背景及其多样的生态环境功能 ,探讨了内陆盐碱化沼泽开发利用中存在的问题 ,如加重区域“三化”趋势 ,造成区域水资源紧张等。为内陆盐碱化沼泽的可持续发展和合理开发利用提供科学依据。
The paper researches systematically the distributions and characteristics of inland saline and alkaline mires in China. There are about 270×10 4hm 2 inland saline and alkaline mires in China, and they mainly distribute in arid and semi arid inland regions, 37 734hm 2 of them are alkaline mires. Furthermore, the formative conditions and various eco environment functions of inland salified and alkalinized mire are discussed. At last, the present problems during development and utilization are investigated and probed into. Because of excess and irrational development, many regional environment problems have been resulted in, such as the deserted, saline and alkaline aggravation in region, the crisis of water resources et al. The results support scientific foundation for the sustainable utilization of inland salified and alkalinized mires in China.
