- 摘要:
- 区域尺度上的主体功能区划研究对区域规划的实施具有重要意义。选择哈大齐地区作为研究区，从生态敏感性、生态系统服务功能重要性和社会经济发展潜力等方面选择了10个指标，采用主成分分析法，以乡镇为单元进行了区域城市土地开发适宜性评价。结果表明，哈尔滨市区及其周边卫星城市安达和肇东的中心镇非常适宜开发，面积占7.08%；齐齐哈尔市区和大庆市区由于受到生态因子的约束而仅其市中心区具有较好的开发适宜性；面积占47.47%的农业地区属于次适宜和边际适宜开发区；西部的农牧交错区由于脆弱的生态背景和重要的生态系统服务功能而不适宜进行开发。该评价结果可以为哈大齐地区的主体功能区规划和区域规划提供参考。
- Abstract:
- Major Function Oriented Zoning (MFOZ) was proposed by Chinese government to find solutions for the conflicts between ecological protection and economic development. This article selects two aspects of ecological restriction such as ecological sensitivity and ecosystem service function importance and combines with social and economic development potential indices to evaluate the city land development suitability of each town of Harbin-Daqing-Qiqihaer region with Principal Component Analysis (PCA) method based on spatial and statistical data. The indices are related to grassland degradation, soil erosion, landscape fragmentation and diversity, Net Primary Production (NPP), arable land quantity, population density, farmer income and road accessibility. The results show that suitability of the capital towns of Harbin and its surrounding cities such as Anda and Zhaodong are high, account for 25 towns and 7.08% area totally, moderate for the capital towns of Qiqihaer and Daqing due to ecological restriction, however, the capital town of Lindian got much higher suitability that can carry industrial transfer of above two cities. Besides, wide agricultural area belongs to sub-suitability and marginal suitability, the agro-pastoral ecotone in the west of study area is not suitable for land development due to its high ecological sensitivity and important ecosystem services functions, land development activities have to be controlled by government in this area. This result can provide references for MFOZ construction and regional planning for Harbin-Daqing-Qiqihaer region.
