摘要
运用景观生态学原理、GIS技术和Fragstats软件,选取了斑块类型水平和景观水平的指数对泰安城区绿地景观格局进行分析。结果表明,研究区绿地景观结构比较单一,绿地空间布局不均衡,破碎度较高;景观指数主成分分析表明,斑块特征指数和空间结构指数为第一主成分指标,LPI和D为第二主成分指标,各类型绿地的综合评价得分,以附属绿地最高,公园绿地和林地最低。同时针对泰安城区绿地景观结构存在的问题,提出了改进建议。
In this paper,patch class and landscape indices were selected to analyse the urban green space landscape pattern in Tai＇an city,based on the principles of landscape ecology,GIS technology and Fragstats software.The result showed that the structure of urban green space was simple,the distribution was uneven,fragmentation was higher.Primary component analysis indicated that patch feature indices and landscape structure indices were the first primary component index,LPI and D were the second.The total evaluation result showed that subsidiary green was the highest,parks and forests were the lowest.Based on these analysis,advice was proposed to improve its landscape pattern.
