| 摘 要： | 本文以经典的级差地租理论为基础,借助GIS空间分析技术,综合分析了岸线资源的自然禀赋、岸线区位条件和岸线产业集聚外部性等表征岸线宜港空间成本-效益因子对岸线级差地租的影响,形成了基于级差地租理论的岸线资源开发价值评价的研究框架。在此框架下,按照经济社会生态效益最大化和开发与保护目标协调化的原则,以镇江市长江岸线资源为例进行了实证分析。研究首先甄别出镇江市岸线资源级差地租为零的岸线,并对其余岸线进行了分级评价,将岸线段依据开发价值进行排序,排序靠前的岸线段近期是建设开发和优化配置的重点,而开发价值较低的岸线段则应留待自然经济条件改善后进行开发利用。根据评价结果提出镇江市岸线资源利用的时空系列,将为岸线资源的优化配置提供科学依据。

| Abstract: | The T-shape of China land exploitation is generally formed by two waterfront lines. The
first one is located in the east of the continent along the west of the Pacific Ocean, and the other is
along the Yangtze River across the country which has been called the Golden Watercourse. A
reasonable and optimized implication of the Yangtze River waterfront resources is now of great
importance as the demand for living, production, and recreation is increasing. In this paper, a new
research framework regarding the evaluation of exploitation and implication of waterfront
resources based on the differential rent theory is proposed. The authors introduced the classical
differential rent theory to this study. Synthesized analysis on the influence of natural conditions,
location qualification, and agglomeration externality to the differential rent of waterfront resources
was performed within the framework and using ArcGIS spatial analysis. All factors under
consideration represent the supply and demand of the waterfront that is suited for building ports. To
begin with, ecological preservation is taken into consideration. Waterfront where the most
important ecological functioning zones, e.g., the source of drinking water, the core of nature
reserve, and famous scenic sites are located is defined as zero differential rent. The portion of the
waterfront can only be used for ecological preservation purposes. Second, waterfront that is not
zero differential rent is then to be valuated by costs of port construction by natural conditions,
including water depth, stability, and the area. In the meanwhile, the potential profit of the ports to
be constructed is considered one feature in the rank evaluation of the non-zero differential rent
waterfront. Influencing factors are traffic accessibility and industrial agglomeration. As a result, the
evaluation rank is of both spatial and temporal meaning formed by sections of waterfront. We
investigated Zhenjiang City in Jiangsu Province within this framework. Zhenjiang maximizes
economic, social, and ecological benefits, and coordinated the relationship between exploitation
and conservation. Evaluation results demonstrated that waterfront of the zero differential rent was
discriminated in the first place, and then the evaluation rank of the rest of the waterfront resources
was assessed. The waterfront sections of high rank are suggested to be exploited only when there is
a high profit. Low rank sections will not be exploited until natural conditions and the economic
environment become improved. The spatio-temporal exploitation sequences of the waterfront
resources in Zhenjiang were consequently defined in a reasonable way. This paper provides a basis
for optimized exploitation of waterfront resources. |
