河北省青龙县葫芦头沟小流域气候的调查报告

通过调查和分析得知,葫芦头沟小流域辐射资源丰富,热量资源充足,降水变率大,易旱易涝。因此,放缓地面坡度、植树种草,减少风蚀强度,提高水土保持能力,从而改善土壤性质和增加空气湿度,是该区进行小流域综合治理的一项重要措施。

Indings Report for Micro-valley Climate in Hulutou Gully of Qinglong of Hebei

It was learned by investigation and analysis that there was abound of radia- nt resources and heat resources in the micro-valley of Hulutao Gully and the precipitetion chang a lot so it was easily drought and easily water logging as well in the area.One of the important measures for tackling the micro-valley in a compre- hensive way is to slow down the grow gradient,plant trees and grow grasses, which can reduce wind erosion and increase the ability of conservation of soil and water,as a result,soil characteritics would be improved and air humidity would be raised.
