基于GIS的神农架国家公园网格管护小区的划分

The division of grid cells of management for Shennongjia National Park based on GIS

从地理分析角度出发,基于对山水林地一体化管理模式的理解与分析,进行神农架网格管护小区划分,以建立神农架国家公园科学管护体系.神农架国家公园网格小区的划分兼顾交通可达性、河网流域、森林体系、行政边界与各种保护区边界等因素.基于DEM数据,利用ArcGIS软件进行水文分析与表面分析,根据河网流域、分水岭、山谷线与山脊线进行区划,在综合分析的基础上,将神农架国家公园划分为18个网格管护小区,有利于神农架国家公园山水林地一体化管理目标的实现和实施科学、高效、统一、规范的管理.

From the perspective of geographical analysis,based on the understanding and analysis of integration of the land, water, and forest, we divides Shennongjia to several grid districts, aiming at establishing scientific management system. The division of Shennongjia National Park grid area takes into account the factors such as traffic accessibility,river network,forest system,administrative boundary and various protected area boundaries. Based on DEM data,we use Arc GIS software for hydrological analysis and surface analysis,and consider the river network watershed,valley line and ridge line to divide the grid area. On the basis of comprehensive analysis,the Shennongjia National Park is divided into 18 grid cells,which is conducive to the goal of the integrated management land,water,and forest for Shennongjia National Park and implement scientific,efficient,unified,standardized management.
