风沙化土地的整治与利用

MANAGEMENT AND UTILIZATION OF THE WIND-DRIFT SAND LAND

风沙化是指干旱和半干旱地带以外地表具有风沙活动,并形成风沙地貌景观的过程。风沙化是继沙漠化研究之后的另一分支。风沙化土地既是可利用的土地资源,又是环境污染的物质源地。对风沙化土地宜采取整治与高效利用并举的措施。建设生物工程和发展生态农业是风沙化土地整治和利用的最佳途径。

The wind-drift sand process refers to the process by which the wind-drift sand activities occur on the ground surface and the wind-drift sand geomorphic landscapes form in the areas outside the arid and semi-arid zones. It is a branch research following the research of desertification. The wind-drift sand land is both an available land resource and a source of pollutants of environmental pollution. For the wind-drift sand land, it ought to adopt the measures of management and effective utilization simultaneously Through investigation and demonstration, it has been found that the construction of biological engineering and the development of eco-ag-riculture are the best ways to manage and utilize the wind-drift sand land.
