| 摘 要： | 在研究了北京市湿地面积赋存量与降雨量、上游水资源量、地下水资源量、城建区面积和GDP等因素的基础上,试图找出影响湿地赋存面积的主要因素,以期为湿地的合理规划和管理提供科学依据。结果显示,北京市湿地动态变化存在显著的自然和人为方面的驱动力因素,自然因素如降雨量,上游来水量和地下水资源量为湿地的退化提供了内在动因,而人类的城市化活动如建成区面积和经济开发则加速了湿地的退化和转化;主成份分析结果显示,第一、第二主成份的累积贡献率92.73%,第一主成份与入境水量、地下水量和降雨量有较大的正相关,贡献度高达93.2%以上;第二主成份与建成区面有较大的正相关,贡献度高达96.6%。

| Abstract: | Based on the actual situation in Beijing's urbanization activities,the paper analyzes the driving factors of both nature and human beings in wetland area reduction.It indicated that the cause of Beijing wetland reduction mainly lied in the urbanization activities such as built-up area and GDP,in addition to natural climate factors such as precipitation,upriver water resource,and ground-water resource.Based on Principal Component Analysis,two components were extracted,with total cumulative contribution rate ... |
