Comprehensive Evaluation for the Soil Fertility Quality of Urban Green Land in Jinan City and and Management
摘要
Abstract
Based on principal component analysis and cluster analysis, the comprehensive evaluation for soil fertility quality of green land in Jinan was conducted. Ten soil fertility indexes of 147 soil samples were analyzed by principal component analysis and six principal components with accumulative contribution rate over 85% were obtained. The scores of the six principal components and comprehensive scores were also obtained. The 147 samples were clustered with comprehensive scores as a measurement and they were divided into 4 ranks by regularly spaced distinct method. Bank 1 was nutrient-richest samples with general scores range of 0.90~2.18 and occupied the position of the highest soil nutrient status and took up 14.91%of the total soil sample;Bank 2 was the nutrient richer with the composite score range of 0.16~0.70 and proportion of 17.01%. Soil nutrient status of Bank 3 was general, the composite score was range of-0.24~0.10 and proportion of 23.81%. Bank 4 was the nutrient deficiency type, the comprehensive score range of-1.04~-0.27 and proportion of 44.22%. According to soil quality situation of urban green space in Jinan city, some measures and suggestions were put forward for soil scientific management.关键词
