基于最小数据集和风险指数的秦岭复垦区土壤健康评价

Shuitu Baochi Xuebao
目的探讨不同植被类型对秦岭复垦土壤健康的影响，评估地上植物与土壤健康的关联，并构建土壤健康评价模型。方法选取杨树林（RY）、松树林（RP）、混合树种林（RM）、女贞林（RL）和葡萄园（CK）5种植被类型，采集不同土层（0~20、20~40 cm）的土壤样品，利用最小数据集（MDS）法结合35项土壤理化和生物指标及4种重金属含量进行分析。结果1）构建最小数据集（MDS）进行土壤肥力评价，包含田间持水量（FMC）、物理性黏粒、pH、土壤有机碳（SOC）、微生物总PLFA、真核微生物PLFA、氮获取酶（NAG）
