【摘要】：随着对资源与环境问题的关注,人们越来越重视森林生态状况及森林生态系统服务的核算。开展森林生态服务的核算过程复杂,需要多个学科,是一项具有探索性、前瞻性工作,需要在理论和实践上有突破。本文对2000-2014年15年国家林业重点生态工程投资量与生态服务价值进行了分析,结果表明生物多样性保护,平均每年占所有价值量的34.2%,涵养水源和保育土壤,分别占25.1%和15.81%,统计结果表明相关系数为0.991,各概率小于0.05的各变量之间呈相关显著。天然林保护工程的特征值即方差贡献为4.78,累积贡献率为53.1885%;退耕还林试点示范工程方差贡献为1.758,累积贡献率为72.723%;提取了7个公因子,评价15年林业的三个产业总值平均水平是完全可行的。
[Abstract]:With the concern of resources and environment, more and more attention has been paid to the accounting of forest ecological conditions and forest ecosystem services. The accounting process of forest ecological service is complex and requires many disciplines. It is an exploratory and forward-looking work and requires a breakthrough in theory and practice. In this paper, the investment amount and ecological service value of national key ecological projects in forestry from 2000 to 2014 are analyzed. The results show that biodiversity conservation accounts for an average of 34.2 percent of the total value each year, conserving water sources and conserving soil. The statistical results show that the correlation coefficient is 0.991.The correlation among the variables with probability less than 0.05 is significant. The characteristic value of natural forest protection project is 4.78, the cumulative contribution rate is 53.18855.The variance contribution of pilot demonstration project of returning farmland to forest is 1.758, and the cumulative contribution rate is 72.723. It is feasible to extract 7 common factors and evaluate the average value of three industries in forestry for 15 years.
