摘　　要：以昆明理工大学呈贡校区和捞鱼河昆明理工大学段及周边景观为研究对象,2016年Google Earth高清影像图作为数据源并划分功能分区,选取景观指数,分析研究区景观格局现状,利用最小耗费距离模型构建直线生态网络,并提出优化建议.结果表明:研究区景观破碎度较高,均匀度较好,离散程度低,聚集度较高,绿地斑块具有优势性,景观格局受功能和人工活动影响明显;绿地面积占比为43.06%,形成了一些生态服务功能较好的生态源点及绿色廊道,但以装饰功能为主的点状绿地较多,增大了绿地的破碎度;部分区域景观阻力较大,可通过提升绿地斑块生态服务质量、增加生态源点数量、生态源点间构建垫脚石等方式增强绿道网络的连通性,使绿道网络充分发挥其生态服务功能.Chenggong Campus of Kunming University of Science and Technology and corresponding section of Laoyu River as well as its surrounding landscape is taken as the study area.The Google Earth satellite image in 2016 is used as the data source for function partition to analyze landscape patterns in the study area by landscape index.The minimum distance model is employed to construct a linear ecological network and some optimization suggestions are proposed.The result shows：（1） The landscape fragmentation rate of the study area is relatively high,the evenness is fairly good,the degree of dispersion low,the aggregation degree relatively high,the green patch advantageous,and the landscape pattern in the study area affected by function and human activity;（2） At present,the proportion of green space in the study area is 43.06 %,forming a number of ecological sources and green corridors with better ecological service function,but there are more dotted green spaces with decorative function,which increases the fragmentation of green space;（3）Part of the regional landscape resistance is large.It is proposed that such measures as improving the ecological service quality of green patches,increasing the number of ecological sources and green corridors,as well as building stepping stones between ecological sources can enhance the connectivity of greenway networks,and make the greenway network fully play its ecological service function.
