This study aims to explore the impact assessment method of geologic engineering activities on the habitat quality of small watershed. This paper utilized remote sensing technology to fetch the land-use change information of the Guobayan Mineral District, a key project in the Baoxing River Basin, and also quantitatively assess the habitat quality there by InVEST model. The assessment results show that from 2000 to 2020:In the Guobayan Mineral District, the land use types mainly changed from woodland to bare land, and the proportion of woodland area decreased by 15.11%, while that of bare land increased by 12.30%;The habitat quality index decreased from 0.9234 to 0.8618, the standard deviation increased from 0.2389 to 0.3134, and the proportion of low-grade area of habitat quality increased by 4.84%, suggesting an slight overall decrease. The proportion of areas with strong habitat degradation increased by 3.40%, and the habitat degradation index increased from 0.0113 to 0.0159, indicating a slight degradation. In conclusion, although the habitat quality of small watershed could be disturbed by human activities, the impact on the environment can be controlled at a very low level through appropriate mining methods, scientific optimization of land-use pattern and effective ecological restoration. |
