中俄边境同江—抚远地区地质资源环境承载力评价与功能区划

    Bearing capacity evaluation and function zoning of geo-resources and environment in Tongjiang-Fuyuan area on the border between China and Russia

    • 摘要: 为促进中俄边境同江—抚远地区地质资源环境保护和新型城镇化建设,在查明区域资源禀赋、水文地质、工程地质、环境地质条件和人类活动方式的基础上,综合运用层次分析法、专家会商法和GIS技术,建立地质资源环境承载能力评价指标体系,并分别进行地质资源环境承载本底和状态评价。通过耦合承载本底和状态评价结果进一步实现承载能力综合评价,同时结合区域社会经济发展需求开展地质资源环境功能区划。结果表明,研究区地质资源环境承载能力整体为中等—强,占全区面积的98%,地下水环境质量问题是制约承载能力的主要因素,界河塌岸等地质灾害风险和易发性较低。基于对评价结果的分析,将研究区划分为生态型、宜居型和农业型3类地质资源环境功能区,提出了加强生态保护修复、改善人居环境、加强面源污染源头管控等措施,为促进边境地区特色旅游产业和农业经济发展提供科学参考。

       

      Abstract: In order to promote geo-resources and environment protection and new type urbanization of Tongjiang-Fuyuan area on the border between China and Russia, a comprehensive approach was employed.This involved analytic hierarchy process, expert Consultation Method, and GIS technology to establish an evaluation index system for assessing the carrying capacity of geo-resources and environment.The evaluation system was based on the investigation of regional resource endowment, hydrogeological, engineering geological, environmental geological conditions and human activity patterns.Furthermore, the bearing background and status of geo-resources and environment were evaluated respectively.The comprehensive evaluation of bearing capacity was further realized by coupling the results of the background and status evaluations, and the geo-resources and environment function zoning was carried out according to the needs of regional social and economic development.The results showed that the level of overall geo-resources and environment carrying capacity in the study area was medium-strong, accounting for 98% of the whole area.The main factor restricting the carrying capacity was the groundwater environmental quality, and the risk and susceptibility of geological disasters such as bank collapse of boundary river were low.Based on the analysis of the evaluation results, the study area was divided into three types of geo-resources and environment functional areas: ecological type, livable type, and agricultural type.Some measures such as strengthening ecological protection and restoration, improving living environment and strengthening source control of non-point source pollution were put forward to provide scientific reference for promoting the development of characteristic tourism industry and agricultural economy in border areas.
