摘 要:在RS和GIS技术的支持下,采用多样性指数、斑块密度指数、形状指数等景观指标,分析了贵阳市二环内1993—2007年的景观动态变化情况。研究结果表明:贵阳市二环内的景观格局基本由林地、灌林地及建筑用地控制,其他景观与其他绿地的基质地位没变,但人为影响因素正逐步蚕食自然景观;研究区正处于城市化进程中,随着经济的发展,人类对绿地景观的干扰日趋严重,景观破碎度增加,形状变化复杂,聚合度呈下降状态;近15年来,景观斑块类型不断相互转化,各种景观类型逐步向其他景观转移,环境绿地及生产绿地部分转移为其他绿地和游憩绿地;生产绿地不断减少,游憩绿地贫瘠,二环区域在规划中应尽可能的增加绿化方式,增加景观的多样性。Based on RS and GIS, the diversity index, patch density index and shape index were used to ana- lyze the spatial landscape pattern developments within the second ring of Guiyang City from 1993 to 2007. The results showed that the landscape pattern was basically controlled by forest land, shrub land and con- struction land. The landscape and green space in other areas were the same as that within the second ring are- a, however, the natural landscape was severely striken by human factor. Recently, the investigated areas were exposed to the rapid urbanization due to the economic development. Green space landscape was seriously influenced and disturbed by human activities, leading to increasing fragmentation of landscape, and the shape became more complex and irregular. During the past 15 years, the landscape patch structures transformed re- ciprocally, and the landscape types gradually transferred to others. The environmental green spaces and pro- ductive green spaces were transformed to other green spaces and recreational green spaces, resulting in the continued decrease in productive plantation area and the shortage of green areas. Therefore, the green styles and landscape diversity are suggested to be increased in the design for the second ring areas.
