Abstract

本文对中国中亚热带常绿阔叶林——甜槠(CastanopsiseyreiTutch) 林76龄成熟林的生境特点、调落物、粗死木质残体、根系生产力、水文学效 应和森林降水化学规律等进行了研究,并对不同林龄甜槠群落的上述特点进 行了对比分折,结果表明: 1试验区年平均气温12.8℃,大气相对湿度86%,降水量2678.78mm,蒸 发量642.9mm;日照时数1434.3b,平均风速引.91m·S-1。地面年平均温度10.8 ℃,地下5、10、15、20cm处年均温度分另为14.8℃、14.5℃、14.8℃、14.5 ℃;全年最高气温37,0℃,最低气湿-8.5℃,地面最高温度51.6...In this experiment, a study of habitat characteristics, hydrological effects, precipitation chemistry, litter fall, coarse woody tebris and root procuctivity of a 76-year-old C. eyrei forest was carried out, and a compartive analysis of an age sequence of C.eyrei stands was undertaken. The results showed as follows: 1 The annual average of air temperature at the experimentaI site in l993 -19...学位:理学博士院系专业:生命科学学院生物学系_植物学学号:B1991210
