不同等级喀斯特石漠化治理的土壤效应研究——以毕节石桥小流域为例

Study on soil effects of treatment for different rocky desertification in karst regions——A case study of Shiqiao small karst basin

选取贵州毕节石桥小流域为样区，以不同等级石漠化生态综合治理土壤效应为研究对象，采用2006～2007年实地监测数据，运用数理统计等方法研究表明：通过治理，土壤物理性质得到改善；土壤温度日较差减小；需要增加土壤中氮素和磷素的投入；土壤酸碱度得到改善，更偏向中性。

The paper takes the soil effects of treatment for different rocky desertification in karst regions as objects and selects Shiqiao small karst basin as a sample area. According to statistics on the monitoring data of 2006 -2007, the paper shows improvement of soil physical properties, decrease of daily range of soil temperature, improvement of soil reaction and requirement of nitrogen and phosphorus.
