滇中坡林地土壤养分与酶活性对等高反坡阶整地的响应OA北大核心CSTPCD
Response of soil nutrients and enzyme activities to contour reverse-slope land preparation in slope forest land of central Yunnan Province
[目的]通过分析等高反坡阶整地对退化坡林地恢复过程中土壤养分与酶活性的影响,揭示该措施生态修复的作用机制.[方法]以昆明市松华坝水源区迤者小流域的退化云南松Pinus yunnanensis坡林地为对象,设置等高反坡阶整地1 a样地(1 a)和10 a样地(10 a),以原状坡面(ck)为对照,比较土壤养分质量分数和酶活性在反坡阶的阶上和阶下及不同土层深度(0～10、10～20、20～30和30～40 cm)的分布差异.[结果]①等高反坡阶整地显…查看全部>>
[Objective]The aim is to reveal the mechanism of ecological restoration by analyzing the effects of contour reverse-slope terrace on soil nutrients and enzyme activities during the restoration of degraded slope forest.[Method]The degraded Pinus yunnanensis slope forest land in Yizhe minor watershed of Songhuaba water source area in Kunming City was taken as the research object.1-year and 10-year contour reverse-slope terrace preparation trials were set up,wi…查看全部>>
