目前国内外对海岸带的界定尚不存在统一说法,虽然海岸带向海范围的界定相对一致,但海岸带向陆范围差异较大。而海岸带向陆范围的界定是海岸带空间合理规划、海岸带区域综合承载力准确评估的重要保证,对海岸带的相关研究起着重要的作用。此外,传统的海岸带界定方法均没有考虑海岸带的动态性及空间差异性,因此,基于Bass扩散模型原理,构建了“湖泊效应”模型,提出了等辐射力曲线的概念,设计了可行的海岸带陆地范围量化方法。以辽宁省为例,结合2001~2012年人口与经济的面板数据,通过GIS与1st Opt软件平台,测度了辽宁省6个沿海城市的海岸带陆地范围,并对其进行了时空差异分析。运用Gompertz模型,预测了辽宁省2013~2020年的海岸带范围,分析了其空间差异趋势。结果表明:1海洋的辐射带动力持续增长,辽宁省海岸带范围随着时间在稳步向内陆扩张;2区域经济较发达的地区,海岸带范围也较广;3大连市和营口市是辽宁省海岸带的增长极;4辽宁省未来8 a海岸带范围将继续向内陆扩张而空间差异将逐步缩小。
At present, there is no unified opinion on the definition of the coast at home and abroad. Although the definition of the coast to the sea is relatively consistent, the range of the coast to the land is quite different. The definition of the coastal zone to the land is an important guarantee for the rational planning of the coastal zone space and the accurate assessment of the comprehensive carrying capacity of the coastal zone and plays an important role in the related research of the coastal zone. In addition, the traditional methods of defining the coastal zone do not consider the dynamic and spatial differences of the coastal zone. Therefore, based on the principle of Bass diffusion model, the “lake effect” model is constructed and the concept of isometric radiation curve is proposed. Feasible method of quantifying coastal land area. Taking Liaoning Province as an example, this paper measured the coastal land area of six coastal cities in Liaoning Province by GIS and 1st Opt software platform based on panel data of population and economy from 2001 to 2012, and analyzed the spatial and temporal differences. Using Gompertz model, the coastal zone of Liaoning Province from 2013 to 2020 was predicted, and the trend of spatial difference was analyzed. The results show that: 1 the momentum of the radiation belt in the ocean continues to increase; the coastal zone in Liaoning Province steadily expands inland over time; 2 the more developed areas in the region have a wider coastal zone; 3 Dalian and Yingkou are Liaoning The growth pole of the coastal zone in Liaoning Province; 4 Liaoning’s coastal zone in the next 8 years will continue to expand inland and the space difference will gradually decrease.
