Evaluation of Forest Ecosystem Service Value in Hanzhong City Based on the Modified Equivalent Factor Method
摘要
Abstract
Based on the secondary survey of forest resources,annual update survey results of forest land map,Hanzhong Statistical Yearbook,Shaanxi Province Grain Purchase Price Monitoring System data and other related data,the unit area value equivalent factor method was used to evaluate the forest ecosystem service value of Hanzhong City in 2021.The results showed that the forest ecosystem serv-ice value in Hanzhong City in 2021 is 195.3 billion yuan.Among the four major categories of forest vegetation ecological service value contributions,broad—leaved forests(including bamboo forests)have an ecosystem service value of 135.3 billion yuan,with the largest contribution to the total value accounting for 69.31%;regulation services have the largest value of 129.9 billion yuan,accounting for 66.51%of the total value.The service value per unit area of forests in the city is 100 865 yuan·hm-2.Forest management in Hanzhong City should be carried out in a scientific and orderly manner following its own succession rules and improve forest quality comprehensively with forest biodiversity increased appropriately,forest tending strengthened,inefficient forest improved,and degraded forest restored.关键词
