| 摘 要： | 区域建设用海是海域使用的一种重要方式。文章以土地与海域集约利用评价为参照,从"投入—产出"的角度出发构建了区域建设用海集约利用评价指标体系,利用遥感解译方法从2017年高分影像中提取并计算了江苏省12个区域建设用海的主要评价指标值,应用TOPSIS模型评价了江苏省沿海已建项目的集约用海现状。研究表明:①江苏省区域建设用海开发利用程度较低,53.2%的土地处于未利用状态,农渔业为面积占比最小的用地类型,江苏省对第二、第三产业的发展更为重视。②已有的开发活动中,人工设施面积较小,建筑与道路等面积占比远小于生态面积,区域生态健康状况良好。③根据指标计算,江苏省区域建设用海集约利用评价得分集中在0.4～0.6,集约利用程度整体较低,不同项目集约化利用程度差异较小,主要原因在于项目投资强度两极分化,道路等基础设施不够完善等。④从不同用海类型来看,交通运输用海集约利用程度最高,其用海结构布局最适宜,效率最高。文章所建指标具有指向性,应用TOPSIS模型进行无须赋予权重,因此更能客观真实地反映江苏省区域建设用海的集约利用情况。

| Abstract: | Sea use for regional construction is an important way of using the sea area.Based on the evaluation of intensive use of land and sea area,an evaluation index system of intensive use of sea for regional construction was established from the perspective of input output.The main evaluation index values of 12 regional construction seas in Jiangsu province were extracted and calculated from high score images in 2017 by remote sensing interpretation method.The TOPSIS model was used to evaluate the current situation of intensive use of sea for coastal construction projects in Jiangsu province.The results showed that: (1) The degree of exploitation and utilization of the sea for regional construction in Jiangsu province was low,53.2% of the land was unused,and the agriculture and fishery were the smallest type of land use.Jiangsu province had paid more attention to the development of secondary and tertiary industries.(2) In the existing development,the area of artificial facilities was small,the proportion of buildings and roads was much smaller than the ecological area,and the regional ecological health was in good condition.(3) According to the calculation of the indicators,the evaluation scores of the intensive utilization of the sea for regional construction in Jiangsu province were concentrated at 0.4~0.6,the overall degree of intensive utilization was low,and the degree of intensive utilization of different projects differed little,mainly because of the polarization of the investment intensity of the project and the imperfection of infrastructure such as roads.(4) According to different types of sea use,the intensive use of sea for transportation is the highest,and the layout of sea structure was the most appropriate and the efficiency was the highest.The indicators built in this paper were directional,and the TOPSIS model does not need to be weighted,so it can reflect the intensive utilization of the sea for regional construction in Jiangsu more objectively and truly. |
