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
