Ecosystem Service Estimate And Realization Of Lashihai Nature Reserve Based On ArcEngine

The content of this article is Ecological services function evaluation of Lashihai Natural Reverse, the technical means is secondary development based on ArcGIS Engine. This paper divides the ecosystem services into three categories according to the classification method based on Human needs, which are material production services, ecological security services, landscape and culture services, then estimate the value of ecological services function of Lashihai Nature Reverse with software programming manner. The paper calculated the net primary productivity with CASA model and the amount of soil conservation with RUSLE model, analyzed the regularity of spatial and temporal distribution of the net primary productivity, and the relationship between retention of soil and vegetation type, slope, elevation, finally, evaluated the three classes, ten indexes of ecosystem services, the result shows as follows.The organic material production value of Lashihai Nature Reserve in2010is165,999,181yuan, nutrient accumulation value is49,659,819yuan; In terms of atmospheric security services, the value of carbon fixation is276,728,180yuan, producing oxygen value is617,309,455yuan; As with soil safety, the value of maintaining soil fertility is645,415,766yuan, reduced abandoned land value is85,731yuan, reduced siltation value is2,673,226yuan; As with water safety aspects, the amount of water conservation is87,229,400.7m3, water conservation value is533,032,699yuan; In terms of landscape and culture services aspects, cultural and scientific value of Lashihai Nature Reverse in2010is20,697,218yuan, leisure and entertainment value is32,033,800yuan.
