基于GIS技术的自然资源空间精准分区方法

Method of Spatial Precise Zoning of Natural Resources Based on GIS Technology

现有的资源区域划分方法存在资源空间划分精准度过低的问题,对自然资源的有效保护效果较差。针对这一问题,本文引入GIS技术,设计一种新的自然资源空间精准分区方法。利用GIS技术对自然资源数据进行精细空间化处理;以阻力因子叠加方法确定自然资源空间阻力面;计算最小累计阻力数值,提取自然资源空间廊道;基于构建的生态安全格局,实现对自然资源空间的区域划分。通过对比的方式证明,新的分区方法应用到实际中可以实现对自然资源空间的精准分区,为自然资源保护策略的制定提供决策依据。

The accuracy of resource spatial division in the existing resource regional division methods is too low,and the effective protection effect of natural resources is poor.In order to solve this problem,this paper introduces GIS technology to design a new method for spatial precise zoning of natural resources.Using GIS technology to process the natural resource data spatially;The spatial resistance surface of natural resources is determined by the superposition method of resistance factors;Calculate the minimum cumulative resistance value and extract the natural resource space corridor;Based on the constructed ecological security pattern,realize the regional division of natural resource space.Through comparison,it is proved that the new zoning method can achieve precise zoning of natural resource space in practice,and provide decision-making basis for the proposal of natural resource protection strategies.
