【摘要】 利用1973-2003年间中国6次森林资源清查资料,以及中国生态系统研究网络长期定位观测资料,建立中国森林生态系统评估指标体系及其定量化方法,并对中国森林生态系统服务功能价值及其动态变化进行评价与分析。结果表明:1973-2003年,中国森林生态系统服务功能总价值变动范围为1.940～2.870万亿元.a-1,单位面积价值变动范围为1.936～2.028万元.hm-2.a-1。20世纪70年代末期以前,中国的森林经营以木材利用为主,森林生态系统服务功能总价值减少,之后随着国家开始重视生态建设而呈逐步增加的趋势;而20世纪70年代末期中国森林生态系统服务功能单位面积价值最大,之后开始下降,直到90年代末期才开始恢复增长。更多还原

【Abstract】 With the 6th forest resources inventory data of China from 1973 to 2003 and long-term positioned observation data of Chinese ecosystem research network,this paper discussed the assessment system and method of quantitative analysis of Chinese forest ecosystem,evaluated and analyzed the service value and their dynamic changes about Chinese forest ecosystem. The results showed that the range of the total value of services function about Chinese forest ecosystem from 1973 to 2003 was between 1.940 × 1012 ～ 2.870 × 1012 yuan.a-1,and the range of the value per unit area was between 1.936 × 104 ～ 2.028 × 104 yuan.a-1. Before the end of 1970s,wood was the major product from the forest management in China,and the total value of Chinese forest ecosystem services function reduced. The total value of Chinese forest ecosystem services function was increasing after China paid attention to the ecology construction. In the end of 1970s,the unit area value of Chinese forest ecosystems system services function was the highest,then declining,until the end of 1990s it began to restore growth.更多还原
