摘    要:对青海大通县北川河流域退耕还林地土壤化学性质研究结果表明,退耕还林中选择适宜的树种及配置比例更有利于土壤肥力的提高。综合考虑土壤化学性质的各项指标,在浅山区以模式C(青杨+枸杞)的N、P、K和有机质含量最高,土壤养分状况最好,而脑山区则以模式F(青海云杉)和模式G(华北落叶松)对土壤化学性质的改善作用比较明显。

关 键 词:退耕还林  土壤养分  配置模式  青海大通

Abstract:The findings indicated that,to choose suitable plants and the disposition proportion in Cropland to Forest were more advantageous to the soil fertility enhancement.Results showed in shallow mountainous area,the N,P,K and organic contents in pattern C(Populus cathayana Lycium chinense) were the highest,and soil nutrient condition was the best;but in high mountainous area,pattern F(Picea crassifolia) and pattern G(Larix principis~rupprechii) showed quite obvious function for improving soil nutrient.
Keywords:conversion cropland to forest  soil nutrient  pattern  Dating County
