小陇山生态站森林生态系统服务功能及其价值评估
Assessment on Value of Forest Ecosystem Services in Xiaolongshan Ecological Research Station
摘要
Abstract
According to the characteristics of structures and functions of ecosystem,evaluating methods of the ecosystem services based on the combination of the class II investigation to forest resource and long-term fixed observation data were discussed. Five typical forest stands in Xiaolongshan Ecological Research Station were studied. Economic values of forest ecosystem services were assessed and analyzed. The results were as follow: 1) The total value of forest ecosystem services was 9 564. 53 X 104 yuan · a-1 , and about 4. 61 X 104 yuan · hm-1 · a-1 ; 2)The value of the six service functions of forest ecosystem was in an order of biodiversity protection＞ carbon fixation and oxygen generation＞ water conservation＞ air purification＞ soil conservation＞ forest nutrition storage varied from 4 150. 40X104yuan · a-1 to 12. 72 X 104yuan · a-1. The value of biodiversity protection, carbon fixation and oxygen generation and water conservation was 92. 9% of the total. 3) The order of forest type was broadleaved forest >Larix spp. >Quercus>P. tabuliformis>coniferous forest. The per unit area value of broadleaved forest and Larix spp. was in the top two.关键词
