以红水河流域水化学资料推算的溶蚀量为依据,分析降水量、岩性、地貌、气温等因素对溶蚀强度的影响.得出影响喀斯特溶蚀强度的主要因素是岩性,其次是降水量,随着地表起伏度的增加溶蚀强度稍有增加.气温对溶蚀强度的影响在本研究区内没有发现明显的规律.

Based upon thecalculated solution ratesbyusing thewater cbemacal data in the Hongshuihe River Basin,the influences of precipiton,lithology,geomorphology and temperature on solutional intensity have been analysed.The resuIts show that lithology is the most important factor aftecting on karst solutional intensity;precipitation is the second. The solutional intensities will slightly increase with surface relief, but the influence of temperature on solutional intensity is not obvious in the area. Finally,an equation to estimte solutional intensity is given as follows:In(x)=1/(4.21/In(P)+0.829/In(lf)+0.295/In(G)-0.636) where P is the annual precipitation,lf is the lithologic mark value,G is the geomorphic mark value, X is the solutional intensity.
