Abstract

The invention provides a detecting method for geographic space distribution uniformity of fragmentation area sampling sites. The method comprises the steps that referring to each sampling site in a sampling area and according to an average sampling area and a Thiessen polygon area of each sampling site, an uniform factor of each sampling site is calculated, and according to uniform factors of allsampling sites in the sampling area, geographic space distribution uniformity of all the sampling sites in the sampling area is calculated. According to the detecting method for geographic space distribution uniformity of fragmentation area sampling sites, the uniform factors of all the sampling sites are firstly calculated, the geographic space distribution uniformity of all the sampling sites inthe sampling area is calculated, and uniform curves of all the sampling sites are generated; the geographic space distribution uniformity of all the sampling sites in the fragmentation area is detected by the uniformity, abnormal sampling sites are determined by the uniform curves to ensure the availability of all the sampling sites in the fragmentation area, and it is conductive to the next redundancy elimination and essence obtaining and mining analysis of the sampling site data.

Description

technical field [0001] The invention relates to the technical field of spatial mapping, in particular to a method for detecting the uniformity of geographic space distribution of sampling points in a fragmented area. Background technique [0002] The fragmented sampling area is generally composed of multiple internal continuous sampling sub-areas, and the sub-areas show different degrees of fragmented distribution, such as agricultural land in a certain area. Whether the distribution of sampling points in the fragmented area is uniform is a key factor for later detection and evaluation of sampling point data, and it is also an important basis for judging whether the later analysis results are accurate. Therefore, it is very important to detect the uniformity of the geographical space distribution of sampling points in the fragmented area. [0003] In the prior art, the following method is usually used to detect the uniformity of geographical space distribution of sampling po...
