The results showed that there covered an area of 193.92 km<sup>2</sup> in the center of Chengdu City. 55.24% of the total area was made up of buildings, covering an area of 107.12 km<sup>2</sup>, 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.展开更多

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.展开更多
