We used three TM images of Ebinur lake wetland: 1990, 2003 and 2010 (August) as the basis data source, We basing on the Markov transfer matrix to analyze the change in value and its transfer tendency of each land use type, and using Fragstats 3.3 software to analyze spatial and temporal change of landscape pattern of our study area in nearly 20 years.Our results show : (1) The land use change of the Ebinur lake wetland is significant: both cultivated land and residential land have expanded significantly, vegetation degraded, and the lake areas shrinked; (3)During 1990-2010, the number of landscape patches increased, the landscape diversity index and fragmentation index increased too, the shape of landscape patches tend to fragment, and the contagion index also declined constantly, which all indicating a fragment trend of landscape pattern of Ebinur lake wetland.

Abstract Since the 21st century, China's rural areas have experienced far-reaching social and economic transformation. Studying the evolution and transformation of rural land use landscape pattern under this background is of great significance to reveal the evolution of human-land relationship in China’s mountains and explore the rural revitalization path. Based on the study of land use change and transition, we put forward the theoretical framework of landscape pattern transition, and establish the rural landscape pattern transformation model of mountain area in southwest China by use of high resolution remote sensing images and field investigation. The results show that: (1) The focus of landscape pattern transformation in the case region is mainly embodied in the reduction of cultivated land, the expansion of orchard and the restoration of woodland. There are obvious differences in landscape pattern transition among different terrain areas in the case region. (2) From 2000 to 2018, the landscape types in the valleys of the study area were gradually diversified, there was a concentration of intensive land use types, and the landscape types in mountainous and hilly area were gradually simplified, and forest land was restored. (3) On the whole, the landscape pattern of the study area has changed from production-oriented landscape pattern to eco-economic landscape pattern and eco-regulatory landscape pattern. The results of case study show that the rural landscape pattern in the mountainous areas of Southwest China has undergone a transformation under the background of land use transformation, which has its own particularity, and verifies the theoretical hypothesis proposed in this paper, so it is necessary to conduct a systematic and in-depth study on this. The theories and methods of this paper are helpful to understand the process of landscape pattern transition in mountainous areas, and provide reference value for the rational use of land resources, ecological management and rural revitalization in similar mountainous areas.

Based on the land use data of 2000, 2010 and 2020, using GIS technology along with landscape ecology methods, this paper monitored the changes in land use and landscape pattern in Wuhan. The findings are as follows: (1) the main features of land use change in Wuhan were the expansion of urban area and the decline of cropland, forest, wetland and water in recent 20 years; (2) forest, wetland and water kept a transfer-out trend while urban kept a transfer-in trend; (3) the fragmentation degree of forest, grassland and urban landscapes decreased from 2000 to 2020; (4) the patch shapes of almost all landscapes tended to be more regular under the human interventions. It is thereby worth reducing the interference intensity of human activities on landscape pattern in the process of urban growth.
