摘　　要：以阿克苏市为例,基于生态安全中的重要影响因子生态绿当量,对城市生态用地适宜性的生态基准量进行更深层次的探讨,并在理论基础上,对研究区不同区域尺度的生态用地类型进行评价并提出优化方案。分析结果表明:阿克苏建制镇和中心城区已完成绿地覆盖率基本建设,但市域生态绿当量只有0.74,需要引起注意并加强环境优化。市域、建制镇和中心城区的绿容率分别为1.8、4.2和3.1,可见市域整体用地布局以及类型需要调整。中心城区人均绿地率只有23.5 hm2/人,需要加强生态服务安全建设。Takes Aksu City as the example,based on the ecological green equivalent of the important impact factor in ecological security,and further explores of the ecological baseline of urban ecological land suitability are studied,and on the theoretical basis.The type of ecological land is evaluated and an optimization plan is proposed with the different regional scales of the study area.The analysis results show that the basic construction of green space coverage has been completed in the town and central city of Aksu,but the ecological green equivalent of the city is only 0.74,which needs attention and strengthens the environment optimization.The green capacity rates of the municipal,institutional and central urban areas are:1.8,4.2 and 3.1.It can be seen that the overall land use layout and type of the city need to be adjusted.The per capita green rate in the central urban area is only 23.5 hm 2/person,and it is necessary to strengthen the construction of ecological services.
