摘要
建立茶林复合生态系统是我国亚热带丘陵山地茶区提高茶叶品质和产量的有效步骤。良好的复合茶园,不仅提高了经济效益、社会效益,而且改善了生态环境。本文通过对不同类型茶园生态系统昆虫类型及数量的初步调查,试图为合理管理茶园提供科学依据。一、研究地点及方法研究地点设在安徽省休宁县洪里乡。该地具有明显的亚热带湿润型气候(Cfa)特征,其特点是温度呈现一种中等强度年周期变化,各月降水量都相当大。
The characteristics of insect kinds and population have been investigated on simple tea garden ecosystem and tea-arbor complex garden ecosystems.The results indicated that the type of vegetation and landform as the most important factors are noticeable influence on the characteristics of insect kinds and population.In general, the Shannon-Weaver diversity index H' may be mirrored the stability of insect and population in tea garden ecosystem, even as the highest H' is in the tea-chinese, chestnut complex garden, the second H' is in the tea-chinese tallow tree complex garden, the least H' is in the simple tea gerden.This conclusion accord with the results of investgation for insect population in tea garden.
