城市岸线资源开发潜力综合评价及优化利用研究——以南昌市为例

Comprehensive evaluation and optimal utilization of urban shoreline resources development potential:taking Nanchang City as an example

作为城市发展的重要资源,城市岸线具有无法替代的生态、生活和生产功能。本文以南昌市为例,选取岸线稳定性、生态敏感度、交通便利度、夜间灯光指数等12个指标,运用层次分析法构建评价指标体系,对赣江南昌段的城市岸线资源开发潜力进行综合评价,分析城市岸线资源利用存在的问题,并提出优化利用策略。结果表明:赣江南昌段岸线资源中,自然岸线约占81.08%,人工岸线约占18.92%;岸线资源开发高潜力区面积约为12.43 km^(2),较高潜力区面积约为157.98 km^(2),中潜力区面积约为128.83 km^(2),较低潜力区面积约为117.24 km^(2),低潜力区面积约为65.16 km^(2);岸线资源开发潜力大,但存在岸线利用程度总体较低、部分岸线利用不合理、岸线开发保护冲突等问题。据此建议从丰富岸线利用类型、优化开发利用方式、保护岸线生态、加强修复治理等方面对南昌市城市岸线资源的利用方式进行优化。

As an important resource for urban development,urban shoreline resources have irreplaceable functions in ecology,living,and production.Taking Nanchang City as an example,the study selects 12 indicators such as shoreline stability,ecological sensitivity,transportation convenience,night light index.Using analytic hierarchy process(AHP)to construct an evaluation index system in order to comprehensively evaluates the potential development of urban shoreline resources in the Nanchang section of the Ganjiang River,then analyzes the problems existing in the utilization of urban shoreline resources and put forward optimal utilization strategies.The results show that:(1)The natural shoreline accounts for 81.08%and the artificial shoreline accounts for 18.92%in the Nanchang section of Ganjiang River.(2)The urban shoreline resources which has highest potential development is about 12.43 km^(2).The higher potential area is about 157.98 km^(2),the middle potential area is about 128.83 km^(2),the lower potential area is about 117.24 km^(2)and the lowest potential area is about 65.16 km^(2).(3)Urban shoreline resources is full of development potential,but it still has many problems,such as low utilization degree of shoreline,irrational utilization of some shoreline,and conflict of shoreline development and protection.(4)The utilization mode of urban shoreline resources in Nanchang should be optimized from the aspects of enriching shoreline utilization types,optimizing development and utilization modes,protecting shoreline ecology,and strengthening restoration and management.
