摘　　要：定位观测和分析结果表明,与纯茶园相比,栗茶间作茶园内影响茶叶产量和品质的小气候条件及土壤条件均得到较大的改善,林分结构较为复杂,且更为完善。从种群生态位基础来看,表现为所研究的各生态因素在地上部分和地下部分呈垂直上的成层性和水平上的交错和镶嵌性;从时间位置结构基础来看,表现为各生态因素在时间位置上部分重叠的协调性。通过对两种类型茶园内春茶期、夏茶期的光照强度变化、气温日变化、大气湿度日变化、净光合速率日变化、蒸腾强度日均值、土壤的有机质含量等方面进行测定比较,为板栗茶树复合生态系统的经营提供了理论依据。The results of located observation and analysis indicate that microclimatic and soil conditions which affect the output and quality of the tea, were improved in the tea garden intercropped with chestnut, and the stand structure was upgraded. From the standpoint of the population niche, the above--ground and underground parts of the ecological factors studied had the characteristics of vertical layering and horizontal intersection and incrustation. According to the structure of the time position, each factor was harmoniously partly overlapping. A comparative study of the ecological factors in the two types of tea gardens in spring and summer respectively, including the variation of light intensity, the daily variation of air temperature, the daily variation of humidity, the daily variation of net photosynthetic rate, the daily mean value of transpiration, and the content of soil organic matter, indicates significant effect of the complex ecosystem on the yield and quality of both tea leaves and chestnuts.
