基于生命周期的区域围填海存量分析方法研究
方剑
天津师范大学
摘要:
为了更加客观地认识区域围填海存量特征,提高围填海存量处置的科学性,本文基于生命周期理论从时间和空间两个维度设计围填海存量分析方法,用围填海存量的年龄反映其持续历史,用围填海存量的时空规模反映围填海存量处置压力。本文选择曹妃甸经济区和天津南港工业区开展实证研究,结果表明:曹妃甸经济区围填海存量的空间规模虽大于天津南港工业区,但后者的时空规模即围填海存量的处置压力要大于前者。这一结果与人们的普遍认识相悖,说明在制定围填海存量处置策略时不仅要从空间上关注围填海存量空间规模,还要从时间维度关注其持续历史。

Research on analysis method of regional reclamation stock based on life cycle
FangJian
Tianjin Normal University
Abstract:
In order to more objectively understand the regional marine reclamation stocks and more scientifically deal with them, a kind of analysis method for evaluating characters of regional marine reclamation stocks considering both temporal and spatial dimensions was designed in the paper based on the life-cycle theory. The ages and temporal-spatial scales of marine reclamation stocks were used to reflect their history periods and disposal pressures respectively. Empirical researches were made on Caofeidian Economic Zone and Tianjin Nangang Industrial Zone. It was shown that Tianjin Nangang Industrial Zone with less spatial scale had larger total temporal-spatial scale of marine reclamation stock than Caofeidian Economic Zone ,which was contrary to people’s common cognition. The suggest was proposed that strategies for dealing with marine reclamation stocks should focusing on not only their spatial scale but also history periods at each engineering status.
Key words:  Life cycle  Age  Reclamation inventory  Space-time scale
