中国热带雨林和季雨林植被分布研究

Research on Vegetation Distribution of Tropical Rainforest and Tropical Monsoon Forest in China

摘要: 目前中国的热带雨林和季雨林生态系统退化严重，确定热带温度界限指标并探究热带雨林、季雨林植被热量和地理分布，对保护和恢复热带森林生态系统具有重要意义。本研究汇总历史研究成果，以年均温22℃及以上为中国热带范围热量指标，基于《中国植被及其地理格局》的框架，结合《中国植被图集(1:1,000,000)》与气象数据等数据资料，对24个热带雨林、季雨林群系进行热量分析并描述其地理分布范围，经验证共有19种群系在热带范围中有分布，其中8种在热带为主要分布。

Abstract: At present, the tropical rain forest and seasonal rain forest ecosystem in China are seriously degraded. It is of great significance to determine the tropical temperature limit index and explore the heat and geographical distribution of tropical rain forest and seasonal rain forest vegetation in order to protect and restore the tropical forest ecosystem. This study summarized the historical research results and took the average annual temperature of 22˚C and above as the heat index in the tropical area of China. Based on the framework of “China Vegetation and Its Geographical Pattern” and combined with “China Vegetation Atlas (1:1,000,000)” and meteorological data, the heat analysis was conducted on 24 tropical rain forests and seasonal rain forest groups and their geographical distribution was described. A total of 19 species have been confirmed to be distributed in the tropical region, of which 8 species are dominant in the tropical region.
