| 摘 要： | 以2004年9月4日Quick Bird遥感影像,辅以实时动态差分GPS RTK技术高精度定位,运用GIS技术和景观斑块谱分析方法,对铜仁市城市绿地景观结构特征进行分析。结果表明:(1)铜仁市城市绿地斑块面积5 857.96 hm2,斑块数量6 503块,规划区绿地斑块面积和斑块数量均大于中心城区;(2)在各种绿地类型中,其他绿地在斑块面积上占绝对优势,其次为农业用地和生产防护绿地,道路绿地面积最小。在斑块数量上,居住区绿地农业用地其他绿地生产防护绿地道路绿地单位附属绿地公园绿地;(3)按绿地斑块面积统计,大于10 000 m2的大型绿地占绝对优势,占整个绿地面积的92.44%,按斑块数量统计,小于500 m2的小型斑块占优势,占整个绿地斑块的69.72%;(4)小型斑块以居住区绿地最多,其次为农业用地和其他绿地等,公园绿地最少;中型斑块和大中型斑块以农业用地最多,大型斑块在面积上以其他绿地最多,数量上以农业用地最多;公园绿地和居住区绿地在各等级绿地斑块中,面积和斑块数量相对较小。综合分析,铜仁市在今后的城市绿地建设中,中心城区内应加强绿化力度,适当将现有的绿地扩大连片,规划区内应合理调整和规划绿地性质,丰富绿地功能特性,注重绿地结构的合理规划,将小型、中型绿地尽可能有效地连片,增加大中型绿地斑块,特别是在与人居密切相关的居住区、单位和街道等周围,增加大中型绿地、大型绿地,以满足人们生产生活对绿地的需求,同时,保护生物多样性,优化城市生态环境。
