兰州市耕地生态系统服务价值估算
|
摘要
生态系统服务功能原则上可被量化估算。由于人们在生态系统服务价值上的辨识度逐渐增加,人们开始关注与重视生态服务系统提供的各类服务价值,这给生态系统服务价值的提升提供了潜在空间。本文在修正兰州市耕地生态系统服务价值当量因子的同时,计算出兰州市2007—2016年耕地生态系统服务价值。结果表明,2007—2016年兰州市生态系统服务价值共减少了2 951万元,说明生态环境受人类社会的经济发展影响较大,并且生态环境一旦受到破坏就难以复原。
Ecosystem services can be quantified in principle.As the value of ecosystem services was increasingly recognized,people begun to pay more and more attention to the value of various services provided by ecosystem services,which provided potential space for the improvement of the value of ecosystem services.In this paper,the equivalent factor of the service value of the cultivated land ecosystem in Lanzhou City was modified,and the service value of the cultivated land ecosystem in Lanzhou City from 2007 to 2016 was calculated.The results showed that the total value of ecosystem services in Lanzhou City decreased by 29.51 million yuan from 2007 to 2016,which indicated that the ecological environment was greatly affected by the economic development of human society,and it was difficult to recover once the ecological environment was destroyed.
