主体功能区划已经成为国家战略,但以行政区为基本划分单元的划分方法仍然没有遵循生态系统的完整性规律。论文将流域生态系统完整性规律引入到主体功能区划思想体系,以淮河全流域30mDEM为数据基础,运用Hydrology模型进行四级子流域划分及科学编码,以此为研究单元从空间开发约束、空间开发强度和空间开发引导三个维度构建空间开发区划指标体系,运用格网方法归并多图层要素进行流域空间开发区划,以精确反映流域覆被特征与图层对应关系,体现流域生态系统的完整性特征,同时也突破了主体功能区县域单元传统划分方法的行政区限制,最终将淮河流域划分为重点开发区、优化开发区、农业发展区、限制开发区、生态保护区,并提出相应的发展对策。 |

Sustained and intensive human activities have significant impacts on the health and security of ecosystems.Although the main functional zoning has been integrated into the national strategy and the ecological direction of China’s regional planning has been clear,the classification method,which divides areas based on administrative function,does not obey the laws of ecosystem integrity.Given the understanding of the relationship between natural laws and human activities,this paper,which takes the 30m DEM of the basin-wide Huaihe River as data basis,introduces the laws of watershed ecosystem integrity into the theory of main functional zoning,and takes four sub-basins of the Huaihe River Basin as research units.Division of basin space development is conducted on condition of evaluation index system and 3D discriminate matrix in spatial development constraints,spatial development intensity and spatial development guidance.The results are shown as follows.(1) Introducing watershed ecosystem integrity law into ideological system of main function division has great theoretical value,and taking Huaihe River Basin as a case to explore space development division has great practical significance.(2) Based on digital topographic map(30 m) and hydrological model,the Huaihe River basin was classified as the fourth stage sub-watershed with scientific codes successfully.(3) The evaluation index system of river basin spatial development division is constructed by integrating various models and operation methods of ArcGIS platform.(4) The Grid Based Method used in this paper can not only reflect the cover features of basin more accurately and scientifically but also remove the administrative data limits,moreover the integrity of the basin ecosystem will be reflected more clearly.(5) The Huaihe River Basin is divided into five types based on the three-dimensional quadrant analysis,namely the important exploitation area,the optimum exploitation area,the agricultural development area,the limited exploitation area and the prohibited exploitation area.Finally,this paper presents the scheme of industrial restructuring.It also provides a scientific basis for making different industrial policies as well as harmonizing the industrial development and the bearing capacity of watershed ecosystem. |
