摘要:
 利用西咸新区2009年Landsat TM遥感影像、2013年与2017年2期Landsat OLI遥感影像,以ENVI5.2、ArcGIS10.0、Frastats4为数据处理平台,运用景观指数和生态风险强度指数对西咸新区2009-2017年景观格局演变和生态风险变化进行分析。结果表明,2009-2017年,西咸新区景观格局发生了明显变化,建设用地增长8.34%,林地增长6.60%,草地面积略有增加。耕地,水域面积均减少,耕地减少最为明显(16.12%),但仍是该区域的主导景观类型,其中绝大部分转化为建设用地与林地。除此之外,各景观斑块类型特征也产生了较大变化,耕地破碎化程度不断增加,优势度降低;建设用地开始趋于大型化、集中化,优势度不断增加;林地破碎化程度增加,优势度上升,其余景观斑块相对比较稳定。蔓延度指数和聚合度指数逐渐降低,香农多样性指数持续增大,西咸新区整体向均质化方向发展。2009-2017年西咸新区生态风险强度指数上升,区域生态安全风险增大。
Abstract:
 Based on the Landsat TM remote sensing images of Xixian New Area in 2009 and the Landsat OLI remote sensing images in 2013 and 2017,landscape metrics and ecological risk index method were applied to analyze the evolution of landscape pattern and ecological risk of Xixian New Area in 2009-2017 by using data processing platforms of ENVI5.2,ArcGIS10.0 and Frastats4.The results showed that the landscape pattern of Xixian New Area changed dramatically from 2009 to 2017.Construction land increased by 8.34%,forestland increased by 6.60%,grassland also increased.Cultivated land and water area all decreased,and cultivated land reduced by 16.12%.Cultivated land was still the dominant landscape patch type of the region.The reduced cultivated land was mainly converted into construction land and forestland.Besides,the characteristics of the types of landscape patches in the landscape also changed significantly: the degree of fragmentation of cultivated land increased and the degree of dominance declined.Construction land tended to be enlarged and centralized,and its dominance increased.The degree of fragmentation of forestland and the dominance also increased.The remaining landscape patches were relatively stable.The contagion index and the aggregation index gradually decreased,and the Shannon diversity index increased continuously.Xixian New Area was developing towards homogenization as a whole.On the other hand,the ecological risk index of Xixian New Area was on the rise and the regional ecological security risk was increasing during 2009-20017.
