Vegetation is the important natural factor in urban landscape, which plays a vital role in improving ecological quality and maintaining ecological balance. This paper starts with greenland system and uses fundamental methods of landscape ecology to analyze the landscape heterogeneity of vegetation in Urumqi. The results show that the landscape diversity index is low, and the distribution of vegetation is unreasonable and uneven. In addition, the line corridor density is not high, the percentage of vegetation coverage and the area of public garden for each person is small. Therefore, some suggestions are put forward to improve the landscape heterogeneity and make the ecological function more effective.
