Suitability Evaluation of Land Development in Hong Kong New Territory Centre based on GIS
摘要
The suitability evaluation of land development is of great significance to measure the potential of land development. Taking Hong Kong New Territory Centre as an example, this paper follows the principles of environmental determinism, integrates physical, biological and cultural attributes in previous evaluation system, reconstructs the land development suitability evaluation model of 11 factors including environmental, social and planning attributes according to the vernacular characteristics of Hong Kong, and assigns weights to each indicator. Using GIS platform, the suitability of land development is analyzed and divided into five grades. What is more, carry on the superposition analysis according to the logical relationship between the three attributes. The results show that: (1) The research area has considerable development potential, more than 30% of the total area. (2) Construction is relatively reasonable and planning capacity is relatively scientific. (3) About 40% of the land is located at the critical value of environmental attribute, which would have certain ecological risks. Finally, the strategy and advice for the future development of the area are proposed based on the above analysis.
