地理国情普查成果在土地资源监测中的应用

Application of geographical national survey results in land resources monitoring

土地资源监测工作的开展必须以精确度较高的数据信息作为基础,否则就会严重影响监测结果的准确性,而目前各省所建立的资源库存在数据信息不够细化且影像信息分辨率较低的问题,因此需要将土地变更数据与普查数据综合起来,明确其之间的相同之处与差异,这样便能够有效提高土地监测的效率。本文就以云南省某县区为例,对普查数据的具体应用方式进行了详细的探讨与分析,可对此方面的研究工作起到一定的指导作用。

The development of land resource monitoring must be based on high precision data information,otherwise it will seriously affect the accuracy of the monitoring results.At present,the resource inventory in all provinces is not detailed and the resolution of image information is low.Therefore,the change data and the census data need to be summarized.Together,we should clarify the similarities and differences between them so that we can effectively improve the efficiency of land monitoring.This paper takes a county in Yunnan Province as an example to make a detailed discussion and analysis of the specific application mode of the census data,which can play a guiding role in this field.
