水体结构健康程度与其功能大小的关系--基于水体生态健康评价研究的整合分析

摘要

Ecological and environmental management emphasize the relationship between ecosystem structure and its function.This relationship has been proved to be positive correlation in terrestrial ecosys-tems.As water issues are becoming increasingly prominent,the researches on health evaluation of water body have increased year by year.But the relationship between ecosystem structure and its function of water body has not received widespread attention and was not clear.This study extracts the scores of the structure and eco-function evaluation modules from recent published data on health evaluation of water body,and applies pearson correlation analysis to study the relationship of them two.The results show that there is a significant positive correlation between structure and eco-functions of water body,which is,however,only significant in the river ecosystems,and not significant in wetlands.%　　目前生态学及相关系统科学强调系统结构与功能间的关系，陆地生态系统的研究已经表明两者存在正相关关系。随着水资源问题的日益凸显，以水体健康评价为目标的研究逐年增多，但水体结构与其功能间的关系并没有得到广泛的关注，两者间的关系也不明确。该研究收集了近年来关于水体健康评价的资料，提取其评价模块中包含的结构和功能模块的评价得分，并采用pearson 相关性分析进行两者间关系的研究。结果表明，水体的结构健康程度与功能大小存在显著的正相关关系，但这种关系只存在于河流水体，而湿地水体中则无此类关系。
