摘要
川中丘陵区水土流失面积为7.71万km2,其中极强度流失面积占流失面积的32.4%,以遂宁市市中区为研究基点,对荒山和陡坡耕地极强度侵蚀区分别采取防治措施,研究其实用技术和改造治理后的综合效益。通过实测资料表明;水土保持作用、小气候变化和经济效益都很显著。
The soil and water loss area of the hilly region in the middle of Sichuan is 77 100km2, 32. 4 percent of it is extremely erosion area. We have just taken Suining urban district as a research base. Some prevention and control measures have been carried out to the extremely erosion area of wasteland and steep hills. We have studied the practical skills and the cotnprehensive benefits after control. The experimental results have proved that the function of water and soil conservation, microclimate changes and economic benefit are all very notable and remarkable.
