济南城市用地景观要素空间结构研究

STUDY OF LAND USE'S LANDSCAPE SPATIAL STRUCTURE IN JINAN CITY

景观空间结构分析是景观生态学研究的核心之一,LUCC研究是当今热点之一.本文将二者结合起来,运用景观生态学原理,借助地理信息系统技术,选取景观破碎度、景观优势度、景观多样性、景观分维数等指标,对济南城市用地不同类型景观要素的空间分布和空间格局特征,分3个圈层进行探讨,最后结合济南市城市总体规划和土地总体规划,针对济南各景观类型的空间分布特征,提出对第二圈层的工业用地适当集中,对于第一、二圈层,要重视在居民区附近开辟零星的绿地和设施用地,具体做到“集聚间有离析”;同时,考虑到经济发展和城市化进程的需要,进一步提高商业用地的规模.

Analysis of landscape spatial structure is landscape ecology＇ s cernel, LUCC is one of hotspots now. This people integrates them. Fragmentation Index, landscape dominance index, shannon＇ s Diversity Index and mean patch fractal dimension were calculated by models and GIS to analyze spatial distribution and spatial structure of landscapes in jinan city grouped three rings in land - use. Finally, we bring urban ecology space planning, realize Aggregate - with - outliers by the spatial distribution of landscapes in Jinan City.
