摘要:

以西双版纳勐腊县为研究区域,分别对茶树林地、10a橡胶林地、20a橡胶林地、30a橡胶林地和次生林地土壤理化性质进行详细的调查研究,并以次生林地土壤性质为背景值,采用土壤退化指数法与土壤综合质量指数法分别对不同林分土壤质量进行定量评价。研究结果表明:1)林分不同土壤性质也不相同,土壤有机质、碱解氮、全磷、全氮和速效钾含量最高值均出现在茶树林地。其中:土壤有机质、碱解氮和全磷含量的最低值均为30a橡胶林地,全氮、全钾和速效钾含量最低值分别为10a橡胶林地、茶树林地和20a橡胶林地。2)不同林分之间土壤质量有显著的差异,土壤质量由高到低的顺序依次为茶树林地>次生林地>20a橡胶林地>10a橡胶林地>30a橡胶林地。西双版纳热带雨林砍伐后,以次生林地为基准值,茶树林地土壤质量有所提高,而不同种植年限橡胶林地的土壤质量均有不同程度的下降。

Abstract:

In Mengla County of Xishuangbanna,a study was conducted on the soil physical and chemical properties of tea forest,10a rubber woodland,20a rubber woodland,30a rubber woodland and secondary forest land in detail,and the soil properties of secondary forest were the background value.Soil degradation index method and soil comprehensive quality index method were used to quantitatively evaluate the soil quality of different stands.The results showed that:(1) The soil organic matter,alkali solution nitrogen,total phosphorus,total nitrogen and available potassium content of the forest were different in the tea forest.The lowest value of soil organic matter,alkali solution nitrogen and total phosphorus content is 30a rubber woodland,the lowest value of total nitrogen,total potassium and available K content is 10a rubber woodland,tea woodland and 20a rubber woodland respectively.(2) There are significant differences in soil quality between different stands,and the order of soil quality from high to low is tea forest,secondary forest,20a rubber woodland,10a rubber woodland and 30a rubber woodland.After the cutting of the tropical rainforest in Xishuangbanna,the soil quality of the tea plantation was improved,while the soil quality of the rubber woodland in different planting years decreased at different degrees.

Key words: rubber forest, soil comprehensive quality index, soil degradation index, quantitative evaluation, Mengla County
