Abstract

Taking Yanchi County of Ningxia as a research area, using GF-1 remote sensing image and Google Earth data, the combination of supervised classification and visual interpretation is used to extract Caragana intermedia Plantation. Based on DEM data and landscape ecology methods, the geographical distribution pattern and landscape characteristics of C. intermedia plantations in Yanchi are analyzed. The landscape unit characteristics and landscape fragmentation degree of different towns and towns are different. The internal division of the patch landscape of C. intermedia plantations in Huamachi Town is complicated. The results show that the total area of C. intermedia plantations in Yanchi accounts for 13.18% of the whole county area, and the distribution of the number and area of plaques varies greatly from north to south. From the geographical distribution pattern, the C. intermedia plantation is widely distributed in areas with low elevation and slow slope. The area with high terrain and steep slope has only a small number of small patches. The internal plaque connectivity of Gaoshawo is better, the landscape of Mahuangshan is more fragmented, and the plaque boundaries of Gaoshawo and Mahuangshan are more tortuous. On the whole, the middle and northern parts of the salt pond with a gentle topography and low elevation are mainly used to build sand control type. In the southern gully hilly area with large area and continuous plaques, the southern gully hilly area is mainly composed of C. intermedia, which is small in area and broken in landscape.
