摘要: 通过对浙西南山区典型土壤进行采集分析,全面摸清土壤养分和耕地地力情况,为山区耕地可持续利用提供科学依据。综合运用地理信息系统、耕地综合地力指数、相关性分析和主成分分析法探究浙西南典型丘陵山区小尺度土壤养分状况、耕地地力评价及其主导因素。结果表明:土壤pH值整体呈强酸性,土壤有机质、全氮、有效磷和速效钾含量较为丰富,土壤容重、阳离子交换量和水溶性盐总量适中。土壤pH值等级集中在Ⅳ~Ⅵ,有机质含量等级集中在Ⅱ和Ⅲ,全氮含量等级集中在Ⅰ和Ⅱ,有效磷含量等级集中在Ⅰ和Ⅱ,速效钾含量等级集中在Ⅰ~Ⅳ。耕地地力等级平均为0.68,一等、二等和三等的耕地地力等级面积占比依次为0.70%、75.90%和23.40%。相关性分析和主成分分析表明,土壤有机质和全氮含量是影响耕地地力的主导因素。

Abstract:

By collecting and analyzing typical soil samples from the mountainous areas of Southwes tern Zhejiang, this study comprehensively investigated soil nutrient status and cultivated land fertility, providing a scienjpgic basis for the sustainable utilization of farmland in mountainous regions. The geographic information system, comprehensive fertility index, correlation analysis, and principal component analysis were integrated to explore small-scale soil nutrient characteristics, evaluate cultivated land fertility, and idenjpgy dominant factors. The results indicated that, soil pH value was generally strongly acidic, while organic matter, total nitrogen, available phosphorus, and available potassium levels were relatively high. Soil bulk density, cation exchange capacity (CEC), and water-soluble salt content were within moderate ranges. Soil pH values were concentrated in grades Ⅳ-Ⅵ. Organic matter content were mainly in grades Ⅱ and Ⅲ. Total nitrogen and available phosphorus levels were predominantly in grades Ⅰ and Ⅱ. Available potassium levels were mainly in grades Ⅰ-Ⅳ. The average comprehensive fertility index was 0.68, with grade Ⅰ, grade Ⅱ, and grade Ⅲ cultivated lands accounting for 0.70%, 75.90%, and 23.40% of the total area, respectively. Correlation analysis and PCA revealed that soil organic matter and total nitrogen content were the core determinants of cultivated land fertility.
