The Analysis On Landscape Pattern At Database Of Land Use

Papers began to speak about the relevance of the concept of landscape pattern, refer the progress of landscape pattern analysis. From the landscape pattern's concept proposal to the study hot spots, landscape pattern analysis has been the main contents of landscape ecology. Stressed the importance of measurement of the spatial heterogeneity. Recognizing that pattern analysis can not be separated from the landscape scale, as it has the scale-dependent to landscape pattern.This article from a technical point of, spoke about the establishment of land-use databases, as well as the raw data involved, including remote sensing images, the basis of maps and text files. And then talked about using software FRACSTATS processing steps and the need to pay attention to some details.Landscape pattern analysis has two kinds of measure :Geo-Statistics and landscpe-index. And this article is used landscape metrics analysis. Landscape index can be highly concentrated pattern of the characteristics of the information landscape. Described in the text about the selected index of landscape principles and techniques.Finally, take the city of Jingmen as examples , which scale on map is l:10000,combined with selected 11 landscape indices,get the conclusions that the best scale is 10m. And classfied and analysised the 11 landscape indices.Landscape pattern deeply based on landscape ecology and statistics,. this article also refer the technology of GIS. From the perspective of land-use database to study the landscape pattern analysis ,and this vision is a new idea about landscape pattern. Therefore, this study not only has some practical value, but also have some theoretical value .Paper is divided into five main contents :The first part is the introduction, refer to main research background of landscape ecology , meanwhile, as well as the theory of advanced research at home and abroad. Also talked about my own understanding of landscape ecologyThe second part is the basic theory, introducing the concepts of landscape and specifically mentioned the importance of scaling.The third part is research methods, the paper used landscape-index, and talked about the landscape index should follow the selection principle.The fourth part is a case study, take the DongBao district as a example, introduced about three characteristics of the study area, and then get the most best suitable scale.The fifth part is the conclusions and innovation, introduce this article had done word and the innovation, pointing out the article's inadequacies .
