无量山国家级自然保护区及其周边地区生态系统多样性测度

利用斑块数、斑块面积、丰富度密度、多样性指数、均匀度指数和优势度指数对无量山国家级自然保护区及其周边地区的温凉性针叶林生态系统、暖热性针叶林生态系统、暖性落叶阔叶林生态系统、季风常绿阔叶林生态系统、中山湿性常绿阔叶林生态系统、半湿润常绿阔叶林生态系统、其他生态系统等15个生态系统的多样性进行了测度。结果表明:研究区15个生态系统中,中山湿性常绿阔叶林生态系统是优势生态系统,其他生态系统是劣势生态系统,其他13个生态系统位于两者之间。此结果符合研究区的实际情况。

Measurement of Ecosystem Diversity in Wuliangshan National Nature Reserve and its Adjacent Area in Yunnan Province

In this paper the ecosystem diversity of 15 ecosystems(cool coniferous forest ecosystem,warm-heat coniferous forest ecosystem,warm deciduous forest ecosystem,monsoon evergreen broadleaves forest ecosystem,wetness evergreen broadleaves forest ecosystem,other ecosystem and others) in Wuliangshan national nature reserve and its adjacent area in Yunnan Province were measured with 6 indexes(patch number,patch area,richness density index,Shannon-Wiener diversity index,evenness index and dominance index).The results were as follows:the wetness evergreen broadleaf forest ecosystem was the preponderant ecosystem,other ecosystem was the inferior ecosystem,and the 13 other ecosystems were all in between preponderant and inferior systems.The results were also in line with the practical situations of the study area.
