中文摘要	随着乌鲁木齐市城市化进程的加快与城市规模不断扩大,城市生态斑块显现景观破碎化现象。以乌鲁木齐市为研究区,以2017年土地利用数据为基础,采用形态学空间格局分析(MSPA)法,对研究区景观格局进行分析,根据斑块重要性(dPC)指数提取生态源地,并根据研究区实际状况构建综合阻力面,采用最小成本路径法识别乌鲁木齐市生态廊道。结果表明:MSPA景观类型中,核心区的面积最大,在研究区西南部和中东部较多;通过计算dPC指数,提取研究区内10块生态用地斑块作为生态源地,同时识别9条重要廊道以及45条一般廊道,主要分布在研究区西南部和东北部;根据源地分布特点,优化生态廊道以后新增了7个规划源地、10条一般廊道,生成了1个踏脚石,以解决研究区西南部和中东部之间的断层现象,从而构建合理的生态网络,使整个研究区的景观连通性明显提升,有利于推动乌鲁木齐市生态文明建设,对经济可持续发展及生态环境的保护具有重要意义。
英文摘要	[Background]In the context of rapid urbanization,issues such as land desertification,soil erosion,and destruction of biodiversity threaten the safety of the regional ecological environment.Building an ecological network is an important means to effectively protect habitat patches.[Methods]This paper took Urumqi as the study area,based on the 2017 land use data,utilized the morphological spatial pattern analysis (MSPA) method to analyze the landscape pattern of the study area and extracted ecological source areas by landscape index,with data such as land use,elevation,and normalized difference vegetation index (NDVI) to construct a comprehensive resistance surface according to the actual situation of the study area,used the minimum cumulative resistance (MCR) model to identify the Urumqi ecological corridors.[Results]The core area of the MSPA landscape type accounted for 73.88% of the total area,it is more in the south and east of the study area,and the area of islet patch was the smallest.By calculating the landscape index,10 core patches in the study area with the highest patch importance index was extracted and used as ecological sources.There were 45 general corridors and 9 important corridors distributed in the southwest and northeast of the study area.According to the distribution characteristics of the source area and the actual situation in the study area,7 new planned source areas and 10 general corridors were added,and an important stepping stone was generated to solve the fault phenomenon of the southwest and middle east of the study area.[Conculsions]Constructing a reasonable ecological network can restore the blocked ecological corridors,significantly improve the landscape connectivity of the entire study area,help protect the living environment of the species and ecological breakpoints,avoid urban soil erosion.It is of great significance to promote the construction of ecological civilization,sustainable economic development and protection of the ecological environment in Urumqi.
