我国湿地土壤资源及其可持续利用

中国湿地土壤资源类型多、分布广、面积大。湿地土壤具有有机质含量高、矿质养分丰富、还原性能强的特点。随着我国人口的持续增长和社会经济的发展，湿地土壤资源正面临质量退化、生态环境功能弱化和生物多样性减少的威胁。在此基础上提出了我国湿地土壤资源可持续利用的对策，即开发利用与保护增殖兼顾；加强农田基本建设、用地养地结合；因地制宜、综合利用，建设湿地生态农业。

THE SOIL RESOURCES OF WETLAND AND THEIR SUSTAINABLE UTILIZATION IN CHINA

The soil resources of wetland have a varied type,wide distribution and vast area in China.Most of them are rich in organic matter and inorganic element as well as reduced-form substance.however,with the development of economy and the increasing of population,soil resources of wetland have been damaged seriously such as qualities degradation,ecological functions weakening and biodiversities decreasing.For the above reasons,some countermeasures for the sustainable utilization of soil resources in wetland are put forward such as (a) to coordinate the relation between exploitation and protection of soil resources;(b)to strengthen the farmland constructions including drainage and fertilization of soil and (c)to develop eco-agriculture according to the natural conditions and the soil characters in each region.
