牡丹江市资源环境承载能力评价

Evaluation on carrying capacity of resources and environment in Mudanjiang City

根据牡丹江市资源环境特征,选取土地资源、水资源、环境和灾害4个要素作为评价指标,建立牡丹江市资源环境承载能力三级评价指标体系,运用GIS空间分析技术,以各要素单项评价为基础开展农业和城镇功能指向集成评价,完成了牡丹江市资源环境承载能力评价。结果显示:农业生产承载能力较高的区域主要分布于宁安市、东宁市,占总面积的48.87%;城镇建设承载能力较高的区域主要分布于宁安市北部、海林市南部及市区,占总面积的44.99%,与现状耕地和建设用地相比契合度较高;68.34%的现状耕地具有农业生产承载能力较高以上等级,79.73%的建设用地具有城镇建设承载能力较高以上等级。评价结果符合牡丹江市实际,可为牡丹江市资源开发利用、生态环境保护及国土空间规划提供参考。

According to the characteristics of resources and environment in Mudanjiang City,four factors,i.e.land resources,water resources,environment and hazard are selected as evaluation indexes to establish a three-level evaluation index system of resources and environment carrying capacity in Mudanjiang City.In virtue of GIS spatial analysis technology,the carrying capacity of resources and environment in Mudanjiang City was evaluated through integrated evaluation of agricultural and urban function direction on the basis of the single evaluation of each factor.The results show that the areas with higher agricultural production carrying capacity are mainly distributed in Ning'an City and Dongning City,accounting for 48.87%of the total area,and the areas with higher urban construction carrying capacity are mainly distributed in the north of Ning'an City,the south of Hailin City and the urban area,accounting for 44.99%,68.34%of the current cultivated land has higher agricultural production carrying capacity and 79.73%of the construction land has higher urban construction carrying capacity.The evaluation results are in line with the reality of Mudanjiang City,and can provide reference for resource development and utilization,ecological environment protection and land space planning of Mudanjiang City.
