摘要
Abstract
Under the combined influence of many environmental factors, the nutrient flow and circulation of ecosystem is quite complex.In this paper, the authors synthetically studied the interaction and interrelation between the nutrient input due to mineral weathering and atmospheric precipitation,the nutrient output due to eluviation and erosion,and the inner circulation because of biological agents. The nutrient balance among input,output and conservation was discussed in a systematic method.In the end, the feedback network model of Experimental Site——Yajiecun Site in Guilin city which indicates the interaction and interrelation of different nutrient components was set up. The network model conduce to restore ecosystem,reasonable use land and develop agriculture in karst areas.关键词
