林地生态产能评价——以河南省为例

The purpose of this article is to scientifically evaluate the production capacity of natural resources and ecological products,on the basis of which natural resource inventories and territorial spatial planning will be carried out,contributing to the realization of the value of ecological products.The methods employed include spatial autocorrelation analysis and comprehensive weighted evaluation method.The results show that:(1)Based on the connotation of production capacity of ecological products,an evaluation framework of production capacity of ecological products was constructed based on"environmental background-vegetation condition-human pressure-human input";(2)The average value of the production capacity of ecological products in Henan Province is 0.341,with higher production capacity in the mountainous areas of South Henan and West Henan,and lower production capacity in the forested areas of North Henan and the plains;(3)the spatial differentiation of the production capacity of ecological products in forested areas of Henan Province is strongly affected by spatial correlation,and the global Moran Index is 0.7.In conclusion,the study proposed a theoretical framework for evaluating the production capacity of ecological products and conducts empirical research on the ecological production capacity of forest land in Henan Province,which has certain scientific and application value.
