闽东南花岗岩地区土壤侵蚀的研究

Study on the soil erosion of granite area in the southeastern Fujian

本文系通过26个径流小区试验,经1985年～1987年3年的测试资料统计分析结果,阐明了在闽东南花岗岩地区的降雨参数在不同坡度,不同生物与工程相结合措施下对水土流失的影响,初步摸出本地区的水土流失规律,并提出生物措施是防治水土流失的最有效办法。为该地区进行有效治理提供了可靠的科学依据。

The results in the paper are from statistical analysis of the examination data out of the experiments on 26 runoff plots during the period of 1985 to 1987 year, it clarifies the effects of the rainfall indexes in the granite area of southeastern Fujian on the soil and water loss under different slope, and different combinations of biological measures with engineer ing, and finds out initially the local rules of soil and water loss,at last it considers the biological measures to be the most efficient method to prevent soil and water loss,the results of which provides reliable basis to conduct effective harness.
