CONCEPT, DISTRIBUTION LAW AND PORMATION MACHANISM OF INLAND SALINE-ALKALINE WETLAND -Taking Songliao Plain for Example

摘要

The paper, taking Songliao Plain for example, studied the concept, distribution law and formation mechanism of inland saline-alkaline wetland. The inland saline-alkaline wetland is distributed over the inland region of arid or semi-arid climate; it is the wet or slightly stagnant environment, forming saline-alkaline soil and salt vegetation and making the geogra phical environment forming complex with an ecosystem of saline-alkaline wetland. The laws of zone nature and non-zone na- ture control the distribution of the inland saline-alkaline wetland that extensively spreads in north part of China and other coun- tries. The inland saline-alkaline wetland is formed jointly by atmosphere, hydrosphere, lithosphere and biosphere including intellectual sphere. Under the special condition, the artificial activity is possibly the key function. In order to improve the human environment, it is a great duty confronting the whole world to rationally transform the inland saline-alkaline wetland. Therefore, we presented an anti-inland theory to promote the environment transformation.
