Abstract:

The coastal zone lies in the overlapping and intersection region of marine and continent, and hence multiple factors have effects on the coastal land use including natural resources, social and economic activities. Therefore, it is of great significance to evaluate the suitability of coastal land for rational allocation, development and utilization in coastal zones. In this paper, we implement the suitability evaluation model (LandUSEM) with the land use dataset of southern Hangzhou Bay in 2010. The frequencies in different combinations of land use types and all evaluation factors are used to evaluate the suitability of coastal land use, separate suitability results from single factors and comprehensive results from different land use types are achieved. Some conclusions drawn from the evaluation results are in the following: (1) The proportion of medium-level suitability is 73.15%, and nearly 25% of the coastal land use is assigned as the critical suitability type or below. It is shown that overall the suitability result in land use of southern Hangzhou Bay performs well, while different suitability categories behave obvious grading divergences. (2) Suitability results in southern Hangzhou Bay has clear characteristics of spatial distributions. Suitability evaluation results in Yuyao and Cixi city outperform that of Zhenhai. Coastal areas denoting medium- and high-level suitability results in Zhenhai is larger than those of Yuyao and Cixi, whereas the critical suitability result of Zhenhai covers far smaller coastal areas than those of Yuyao and Cixi. The explanations for that is partly because of local industrial structures in each city. (3) Each land use type has suitable development status in varying degrees. Some 96.45% of urban and rural construction land is estimated as critical suitablility and above above, and moreover the critical suitability takes 70.91% of the construction land. Some 89.31% of shoal land has critical suitability and above, and among that 80.72% is highly suitable. This indicates that the shoal conditions have good potentials in land use, and proper and timely actions are encouraged to transfer shoal lands into agricultural lands or urban construction lands to satisfy the needs from economic development in southern Hangzhou Bay.
