Study on landscape spatial pattern in the center of chengdu city is based on the Landsat-8 image by using 3S technique and spatial pattern analysis software Fragstats 3.3. The results showed that there covered an area of 193.92 km2 in the center of chengdu city. 55.24% of the total area was made up of buildings, covering an area of 107.12 km2, and the overall landscape of impervious ground-based. There were 22,666 patches;29.67% of the patches were roads. The human interference of buildings, roads and green space was a maximum;fragmentation of the highest was green space. The fragmentation of overall urban landscape was high;the diversity was low;the value of Shannon’s diversity index was 0.63;the value of Shannon’s evenness index was 0.70. All kinds of landscape distribution were not balanced, and lack of connectivity. This research puts important reference for creating good urban landscape space and restoring the natural ecological environment in the western regions of China.

Journal of Landscape Research 2016年第3期8卷 101-104页

作者： LIU Xin YANG Shu chengdu Agricultural College

Taking 5 representative comprehensive universities in different locations of chengdu city for example, this paper analyzed plant composition on the 5 campuses, i.e. Sichuan University, University of Electronic Science and Technology of China, Southwest Jiaotong University, Southwestern University of Finance and Economics, chengdu University of Technology, as well as the application ratio of trees, shrubs, grasses as well as ground cover, coniferous plant, broad-leaved plant, deciduous plant, and evergreen plant. Plants in the 3 functional areas of the 5 campuses were investigated, application frequency of plants in each functional area was recorded and measured, and application differences of plants in different functional areas were compared and distinguished. Species confi guration, application frequency and species type, species richness, diversifi ed ornamental effect and life form on the campuses were analyzed.

chengdu city is in the period of rapid urbanization and industrialization, and the disturbance derived from human activities on environment is increasing remarkablely in recent 20 years. The pressure on environment, economy and population is also increasing and land use in chengdu has changed enormously. As struc- ture and function of land ecological system change obviously, sustainable development of land productivity has been an important goal and strategic task from now on, and it is necessary to systematically research land ecological carrying capacity based on ecological footprint. The ecological footprint of chengdu city in the past ten years was calculated and analyzed from the spatial and temporal aspects according to statistical data from 1998 to 2008, as per ecological footprint method, ecological carrying capacity and the GIS spatial analysis method, and regression analysis method. The ecological footprint and ecological carrying capacity values from 2009 to 2019 in chengdu city were predicted through calculation results in the past ten years. The results show that the ecological footprint and ecological deficit of land use from 1998 to 2008 increased in chengdu city. The ecological deficit of land use within the city center was in high levels in the past ten years, and the ecological footprint kept raising, especially in areas, such as Shuangliu, Chongzhou, Qingyang among 9 city areas, 4 counties and 6 districts in chengdu city. There is fanlike distribution of ecological deficit of land use. Analysis shows that the social and natural ecological system is uneven distribution, which is not in sustainable de- velopment situation. The results of the study show that the economic, social and natural ecological system in chengdu city is not sustainable, and the ecological foot- print is uneven distribution. The analysis of the dynamic change of land ecological carrying capacity in chengdu city is very important for city government in the pro- cess of the vigor
