【摘要】 以2008年覆盖惠城区的SPOT5遥感影像为数据源,经过监督分类和人机交互式解译,获得研究区土地利用景观分类图。通过景观指数的计算,定量分析惠城区作为珠三角东缘低山丘陵区土地利用景观格局特征及其成因。结果表明:惠城区的土地利用景观格局连通性较强,多样性和均匀度较高;但景观的形状较为复杂,人为干扰较大,稳定性不强;各土地利用类型破碎化程度差异较大。应重视通过构建可持续农业的景观生态模式、借助规划等手段、调整植被结构和发挥旅游资源优势等系列措施,以提高景观的稳定性和适应性。更多还原

【Abstract】 Based on SPOT5 remote sensing image in 2008,the landuse landscape map of Huicheng Destrict was made by manual and supervised interpretations with ENVI and ArcGIS software.Through the calculation of landscape indices,the formation of landuse landscape pattern in Huicheng District,which as a case of hilly area of Pearl River Delta,was analyzed quantitatively.The results indicated that connectivity of the landuse landscape pattern was stronger;diversity and evenness indices both were higher.Due to the human impacts, however,the landscape shape was more complicated and the stability was not good enough;the fragmentation degree differed greatly in every landuse type.In order to improve stability and adaptability of the landscape and realize the sustainable use of land resources,some countermeasures were put forward as the following: constructing the landscape pattern of the sustainable agriculture,using the planning measures,adjusting the vegetation structure,taking advantage of the tourism resource,and so on.更多还原
