The Application of the Tiangong-2 Wide-band Imaging Spectrometer Data in the Ecological Environment Evaluation - A Case Study of Kunming

Kang Liu, Bangyong Qin, Shengyang Li

Abstract

As a new type of remote sensing data source, the Tiangong-2 image data have several advantages and can be applied in various fields, of which one application is the ecological environment evaluation. In this study, the ecological environment status in Kunming, a major city of “The belt and Road Initiative”, is performed using data provided by the wide-band imaging spectrometer on Tiangong-2. The ecological environment evaluation system is established based on The Criterion for Ecosystem Status Evaluation, in which the vegetation coverage index, soil index and slope are used as the evaluation indicator. The ecological environment status in Kunming is evaluated and classified into four grades including excellent, good, medium and poor based on the “3S Technology”. The result shows that the ecological environment in Kunming is good, of which 62.75% is excellent or good grade and distributed in the area with high vegetation coverage, 30.84% is medium grade and distributed in the mountainous areas or the Dian Lake, and 6.40% is poor grade and distributed in the north of Dian Lake or other built areas. Strengthening the ecological protection and restoration of Dian Lake and its surrounding areas will help to improve the overall ecological environment quality of Kunming.
