Abstract

Abstract: Development potential assessment of land resource plays foundation for land use planning. Therefore, finding out the land potentiality of economic production capacity is a key proposition of allotting land resource in the background of urbanization and industrialization. In this study, the index system was established based on natural condition, ecological sensitivity, economic development and spatial structure, moreover, fuzzy comprehensive evaluation and analytic network process method were adopted respectively to value each index and weight. This study figured out potential value by map algebra in ArcGIS and divided study area into four potential districts with natural break method. The conclusions show that: (1) low potential district has the area of 237.14 km², taking the percentage of 17.73%; medium potential district has the area of 323.08 km², taking the percentage of 24.15%; high potential district has the area of 473.34 km², taking the percentage of 35.38% and extreme high potential district has the area of 304.27 km², taking the percentage of 22.74% respectively. (2) According to the analysis of land use types in different land potential districts, transport land and natural reserved land area reach the peak in extreme high potential district and decrease from the extreme high potential district to the low potential district; cropland, rural-urban construction land, other agricultural land and other construction land have the biggest ratio in the high potential district and mostly distribute in the extreme high or the high potential district; garden plot, water surface and water conservancy land are basically distribute in the medium potential district, while tidal flat and woodland distribute in the medium and low potential district.(3) Land development potential in coastal zone of these cities have different characteristics, which are specified as: the potential district in Yuyao county belongs to further-promotion type, the potential district in Cixi county belongs to balance development type and the potential district in Zhenhai belongs to high potential quality type.

Key words: land development potential assessment, analytic network process, fuzzy comprehensive evaluation, coastal zone, the southern bank of Hangzhou Bay
