【摘要】：土地资源是生活、生产的立足之本。浙江素有“七山一水两分田”之说,人多地少的矛盾长期以来一直是制约浙江社会经济发展的主要因素之一。浙江省丰富的滩涂资源是重要的后备土地资源,通过科学合理地开发利用滩涂资源,在寸土寸金的沿海地带开拓发展空间,对于浙江经济社会快速可持续发展具有至关重要的作用。目前,浙江省滩涂围垦呈现建设规模不断扩大、围成面积不断递增的趋势,但是从全省围垦区开发利用的普遍情况看,因缺少前瞻性的整体规划,各地不同程度地存在开发利用模式粗放、功能定位与布局不合理、资源节约集约不足、生态环境重视不够等问题,导致滩涂围垦区开发利用存在资源浪费、效益效率低下、生态环境遭受破坏等一系列问题。因此,对建成的滩涂围垦区进行科学合理的功能定位和开发利用,是提高效益投资比、实现综合经济效益最大化的的关键。上虞区隶属绍兴市,其围垦区是绍兴滨海产业集聚区的重要组成部分。上虞区滩涂围垦历史悠久,围垦区土地开发利用方式具有明显的时代特征。本文先对国内滩涂围垦、土地开发利用等政策法规、调研报告等进行收资调研以及对上虞实地调研等,提出制约围垦区土地开发利用的约束条件。再通过上虞县志、上虞水利志等历史资料以及多期遥感影像的解译数据分析上虞区在不同的经济社会发展阶段围垦区土地开发利用方式的演变过程,研究影响这种变化的关键因子。采用单目标线性规划法结合层次分析法、特尔菲法构建基于安全、资源、生态环境等约束条件的围垦区土地开发利用结构优化模型,实现为上虞围垦区土地开发利用结构提供开发利用指导方案等功能,完成土地资源的合理配置以达到综合经济效益最大化。本文建立的综合经济效益最大化的围垦区开发利用方式数学优化模型,其研究方法和结果可为沿海地区滩涂围垦区土地开发利用的优化提供参考和借鉴,具有较大的推广价值。
[Abstract]:Land resources are the basis of life and production. Zhejiang is known as "seven mountains, one water and two fields", the contradiction of people, land and land has been one of the main factors restricting the social and economic development of Zhejiang for a long time. The abundant tidal flat resources in Zhejiang Province are important reserve land resources. Through the scientific and rational exploitation and utilization of the tidal flat resources, we can open up the development space in the coastal areas with an inch of land and an inch of gold. It plays an important role in the rapid and sustainable development of Zhejiang economy and society. At present, the tidal flat reclamation in Zhejiang Province is showing a trend of increasing construction scale and increasing area. However, from the general situation of development and utilization of the reclamation areas in the province, due to the lack of a forward-looking overall plan, Some problems exist in various areas, such as extensive development and utilization mode, unreasonable function orientation and distribution, insufficient conservation of resources, insufficient attention to ecological environment, etc., which lead to waste of resources and low efficiency in the development and utilization of the reclamation area around the tidal flat. Ecological environment has been damaged and a series of problems. Therefore, it is the key to improve the ratio of benefit to investment and realize the maximization of comprehensive economic benefit to carry out scientific and reasonable function orientation and development and utilization of the constructed reclamation area. Shangyu District belongs to Shaoxing City, and its reclamation area is an important part of Shaoxing Binhai Industrial agglomeration area. Beach reclamation in Shangyu area has a long history, and the land development and utilization mode in reclamation area has obvious characteristics of the times. In this paper, the policies and regulations of land reclamation, land development and utilization in China, the investigation report and so on, and the field investigation on Shangyu are carried out, and the restrictive conditions are put forward to restrict the development and utilization of land in the reclamation area. Based on the historical data of Shangyu County Records, Shangyu Water Conservancy Records and the interpretation data of multi-period remote sensing images, the evolution process of land development and utilization mode in different economic and social development stages in Shangyu area is analyzed. The key factors affecting this change are studied. The single objective linear programming method combined with the analytic hierarchy process (AHP) was used to construct the optimal model of land development and utilization structure based on security, resources, ecological environment and other constraints. In order to maximize the comprehensive economic benefit, we can provide the guiding scheme for the development and utilization of land in Shangyu Reclamation area and complete the rational allocation of land resources. The mathematical optimization model of comprehensive economic benefit maximization is established in this paper. The research methods and results can provide a reference and reference for the optimization of land development and utilization in coastal beachland reclamation area, and it has a great value of popularizing.
