Research on the Spatial Pattern Changes of Qinling's Ecological Environment in Past 20 Years Based on Remote Sensing
The changes of the ecological environment can be shown by the vegetation changes by remote sensing. Using RS and GIS technologies, Landtrendr algorithm, this paper analyzed the land use pattern, vegetation coverage change, and forest land disturbance and restoration of Qinling Mountains in the past 20 years, and further discussed the driving force of its change. The results show that in the past 20 years, the land use in the Qinling Mountains has been dominated by forest land, the overall vegetation coverage is in-creasing, and the urban area is decreasing. The Landtrendr monitoring shows that the forest land disturbance cases mainly exists in ur-ban areas, the development in Xi'an is earlier than other areas, the classification results are good and human disturbance is the main driving force of forest land change. The above results show that the construction of Qinling Mountains ecological civilization has a-chieved certain results, providing a scientific basis for Qinling Mountains ecological environmental protection.
