生态产品价值实现的适宜性评价与路径配置

Suitability evaluation and path allocation of ecological product value realization

科学评价生态产品价值实现适宜性对选取生态产品价值实现路径、优化国土空间开发格局具有重要参考价值。以内蒙古鄂尔多斯市为例,借助ArcGIS平台,采用层次分析法、多要素空间叠加法等,在核算生态产品价值基础上,从开发潜力与生态功能重要性两个角度评价生态产品价值实现适宜性,进而对价值实现路径进行配置。结果显示:1)2020年,鄂尔多斯市生态产品总值为1423.67亿元,空间分布上呈现东北-西南方向价值高,西北-东南方向价值低的特点。2)生态产品开发潜力高值区集中于生态本底条件较好的东北部;生态功能重要性总体呈现南高北低的特点,高值区在东南部有明显聚集。3)生态产品价值实现适宜区、基本适宜区面积占比分别为16.71%、29.80%,主要分布于鄂托克旗西部、准格尔旗、杭锦旗等。基本不适宜区、不适宜区面积占比分别为40.98%、12.51%,主要分布于鄂托克前旗、鄂托克旗中东部、乌审旗等。4)路径选择上,适宜区以产业生态化为主,基本适宜区以生态修复为主,基本不适宜区以生态产业化为主,不适宜区以生态补偿为主。生态产品价值实现的适宜性评价搭建起了生态产品价值量化与转化的桥梁,能够为地区国土资源开发与布局提供具体性参考建议。

Scientifically evaluating the suitability of ecological product value realization has important reference significant for selecting the path for realizing the ecological products value and optimizing the pattern of territorial development.Taking Ordos City in Inner Mongolia as an example,with the help of ArcCIS platform,the analytic hierarchy process and multi-factor space superposition method were used to evaluate the suitability of ecological product value realization from the perspectives of development potential and the importance of ecological function based on the calculation of ecological product value,and then the value realization path was configured.The results showed that:1)The total value of ecological products in Ordos was 142.367 billion yuan in 2020,the spatial distribution showed a high value in the northeast-southwest direction and a low value in the northwest-southeast direction.2)The areas with high value of ecological product development potential were concentrated in the northeast with better ecological background conditions.The importance of ecological function was generally higher in the south and low in the north,and the high value area was obviously clustered in the southeast.3)The proportion of suitable areas and basic suitable areas for realizing the value of ecological products was 16.71%and 29.80%,respectively,mainly distributed in the west of Otog Banner,Junge Banner,Hangjin Banner,etc.The proportion of basic unsuitable area and unsuitable area were 40.98%and 12.51%,respectively,which were mainly distributed in Otog Front Banner,the central and eastern part of Otog Banner and Wushen Banner.4)In the path selection,the suitable area was dominated by industrial ecology,the basic suitable area was dominated by ecological restoration,the basic unsuitable area was dominated by ecological industrialization,and the unsuitable area was dominated by ecological compensation.The suitability assessment of ecological productsvalue realization builds a bridge for the quantification and transformation of ecological product value,and can provide specific reference suggestions for the development and layout of regional land and resources.
