| The relationship between the change of landscape patterns and human activities has become a research hotspot in ecology.Relying on the strategic background of my country’s "The Belt and Road Initiative",China and Myanmar formally proposed the construction of the China-Myanmar Economic Corridor in 2017.The corridor has a prominent regional strategic position,a sensitive ecological location,and an important geographical location.The protection of its ecological environment and the change of landscape patterns affect the future development of the corridor and the production and life of the people along the route of the corridor.This paper takes 22 counties and cities along the China-Myanmar Economic Corridor as the main body,collects local natural,economic,and social dataand information,uses the land cover data of the three year’s phases of 1995,2005,and 2015,and applies ArcGIS10.5 software to view the landscape.Area,spatial distribution and dynamic change characteristics were analyzed;the landscape pattern index of the corridor belt was calculated in the landscape pattern analysis software Fragstats4.2;the landscape pattern driving factor and Logistic model were used to analyze the landscape pattern driving force of the study area;The model of CA-Markov was used to predict the landscape pattern of the China-Myanmar Economic Corridor in 2025,so as to explore the degree and trend of its landscape pattern change,and to analyze the reasons for this change.The research results will provide with the scientific basis and theoretical support for the ecological environment protection,sustainable development,sustainable development,and also for the urban and rural planning and land management of the China-Myanmar Economic Corridor..The main conclusions of the study are as follows:（1）The landscape characteristics and change patterns of the study area are generally reflected as the following:the landscape pattern has changed significantly,and the woodland has continued to decrease and the decrease area was the largest（1207km2）,of which 77%was converted to farmland;the farmland at first stage increased and then decreased and with the largest increase area at all,that was 560km2;the grassland shown a trend of decreasing at first stage and then increasing;the area of water,bare land and urban land continued to increase,of which only urban land was transferred to 477 km2,of which 85.43%was the conversion of farmland,which shown the most dynamic degree.（2）At the landscape level,SHDI increased from 0.88 to 0.90,SHEI increased from 0.49 to 0.50,CONTAG decreased from 67.6 to 66.9,and AI decreased from 93.08 to 92.99,reflecting the increased spatial heterogeneity of patches and continuous character of patches decreased,the level of diversity rised,the degree of human interference continued to increase,and the degree of fragmentation increased.At the level of landscape type,farmland has changed from the previous relatively scattered trend to relatively concentrated;the degree of connection between water areas has increased,and the patch shape has been simplified;the degree of aggregation of grassland has decreased,and the landscape has become fragmented;the LSI of woodland has been reduced from 39.89 to 39.01 The plaque shape was simplified,MPS was reduced from 4521 to 4212,PD and NP were both increased,spatial heterogeneity,and the degree of fragmentation was increased;PD and NP of urban land were increased,LSI was increased from 17.08 to 29.16,and AI was increased from 73.44 Reduced to 70.18,it was learned that although urban land has increased significantly,its degree of connection was low and tends to be scattered.（3）The change of the landscape pattern of the China-Myanmar Economic Corridor in the past 20 years has been affected by the combined effects of natural factors（slope,elevation,average annual temperature,average annual precipitation,distance from rivers and distance from roads）and social economic factors.The social economic factors affecting the landscape change was increased day by day,and more prominent in the year of 20052015.（4）The change of landscape pattern in the study area in 2025 is predicted.During this period,the main landscape types will be still woodland and farmland,and the area will decrease to varying degrees.In addition,the dynamic degree of urban land use will still be the largest,which is expected to increase by 2 times.,Up to 1659 km2.Other landscape types will be little change in the spatial structure,the water area and grassland will be decreased,and the bare land will be not changed. |
