以6年生女贞人工林为研究对象，探讨稻草与砂石覆盖和密度调控（50％与75％树木移除）对其光合特性和土壤性质的短期影响。结果表明，树木移除可提高林下土壤和林分内大气温度，降低林下土壤含水量及林分内大气相对湿度，从而提高植物的净光合速率；覆盖对土壤及大气水热状况具有调节作用，其中，稻草覆盖效果最为显著；稻草覆盖和凋落物覆盖可提高林下土壤肥力和微生物量碳的含量。在强度树木移除与稻草覆盖、强度树木移除与砂石覆盖条件下，女贞水分利用率提高效果最为明显。

The aim of this study was to investigate the short-term effects of removing(50% and 75% of frees removing)and mulching on photosynthetic characteristics and the soil properties of a 6-year-old Ligustrum lucidum plantation.The results showed that thinning could increase air temperature in forest stand and soil temperature un-der forest,reduce soil water content and relative humidity,which increased net photosynthetic rate.In addition, mulching could regulate the temperature and water content of soil and air.And the effect of straw mulching was most obvious.Straw and litter mulching could improve soil nutrient status and the contents of soil microbial biomass carbon observably.Water-use efficiency of Ligustrum lucidum could be significantly improved by intensive removing with straw mulching or intensive removing with gravel mulching.
