摘要
对雷州半岛短轮伐桉树林地砖红壤的各肥力因子进行系统的数值化处理 ,通过隶属度函数模型和偏相关分析 ,确定了林地土壤各肥力因子的隶属度值及其权重 ,根据加乘法则 ,对雷州半岛短轮伐期桉树砖红壤的综合肥力水平进行了分析和探讨 ,研究结果显示 ,雷州半岛林地砖红壤其土壤综合肥力水平并不高 ,绝大部分土壤属于较低或极低水平 ,与实际土壤生产水平完全吻合。图 1,表 4 ,参 8。
Systematical digitization processing of various fertility factors in latosol of Eucalypts land of short rotation in Leizhou Peninsula was made in this paper Through membership function and partial correlation analysis, the membership degree and weigh of soil various fertility factors were determined and the integrated evaluation of soil fertility was done Results indicated that the comprehensive of latosol under Eucalypts was not high For most of the soils, the fertility levels were grouped in lower or very lower grades, identified completely with the practical soil productivity
