| Sustainable development of the the ebinur lake Ecological function basin area.In this paper,on the basis of the information of remote sensing images in 2005 and2015,using the ENVI to remote sensing image processing,ARCGIS10.0 software for landscape classification,and then through the landscape dynamic,the information office of the index such as 2005 and 2015 two issue of land use data,and using Fragstats 3.3 your choice of landscape pattern index calculation,analysis of the changing rule of the ebinur lake wetland and the surrounding landscape pattern,explore the natural,social,economic and other factors.Using IDRISI Andes 17.0software support CA-Markov model was constructed,the landscape pattern of ebinur lake basin in 2025 core simulation forecast,according to the simulation results can promote the sustainable development of the wetland are discussed.This article analyzed the present situation of the landscape pattern of the ebinur lake wetland and its surrounding and change rule,and the influence factors of the formation and change of landscape pattern to do further exploration,on this basis to predict the future of the ebinur lake wetland and the surrounding landscape pattern,and put forward to promote the ebinur lake wetland and the surrounding ecological protection and sustainable development of MODS system suggestion.The following conclusions can be drawn:(1)Through land use dynamic change rule and information entropy of the ebinur lake wetland from 2005 to 2015 and its surrounding land use type change present tends to increase with decreases,less extent,unused K value is 2.34%.Woodland is-6.94%.In terms of the increase,the maximum dynamic attitude value was grassland(17.02%),the construction land and water area reached 16.17% and14.34% respectively,and the cultivated area had a small increase in the attitude value of 5.88%.In general,land use is moving in an orderly direction.Ebinur lake basin wetland reserve and its surrounding in 2005,the information entropy of land use is 1.074,the information entropy of 0.7792 in 2015,compared with obvious drop,from the macroscopic Angle to analyze,2005-2015,a greater degree of land use in order the ebinur lake basin core,thanks to the increase of the proportion of grass,a large number of utilization of unused land.(2)From the analysis of the landscape pattern index of the research area,the landscape pattern structure of the core area of ebinur lake basin changed significantly from 2005 to 2015.The LSI and CONTAG index reflected the degradation of thesystem and reduced the complexity,which means that the landscape pattern of the ecosystem was excellent in general.However,from the perspective of landscape type,the increase of AREA-MAN in low middle coverage AREA was relatively large,but NP was slightly reduced.High coverage of AREA-MAN and NP is increasing,indicating that the grassland fragmentation is aggravated and landscape pattern becomes more complex.From the analysis of the shape characteristics of the landscape type,the unutilized land belongs to the dominant type,the change is the largest,the boundary tends to rule but unstable,the woodland and grassland and the water body tend to rule,the cultivated land tends to be irregular.The rapid expansion of urban construction makes the landscape patch shape is more complex,different types of patch area tend to be more uniform,in the whole landscape pattern the advantages of the unused land and grassland landscape patches effect is obvious.(3)From the transfer of land use transfer matrix can know grassland and unused land into transfer area and the area are of great value,but the grass-1312 net change quantity,the grass turned out great,unused capacity of 1284,net change into a very large.The grass on the edge of the ebinur lake wetland and wetland said role bureau,unused in the saline-alkali land and grassland and sandy land,lakes,beaches,and the correlation of the gobi is big,transfer contact relationship is very strong.The area of woodland and water area increased obviously,arable land and construction land decreased obviously.(4)To analyze the change of landscape type area from the terrain factors of natural elements,including elevation,slope and distance of river network.The change of landscape pattern is analyzed from the social and economic factors,such as transportation network,policy,population and historical evolution.Most of the landscape types distribution at lower elevations and lower grade range,unused altitude and gradient distribution in the lower,arable land in increasing distribution in altitude,woodland and grassland area distribution with the altitude and slope increases.(5)Using CA-Markov model for the study area in 2025,to simulate the landscape pattern and forecast results show that the growth of cultivated grassland land is the biggest landscape types,the area is significantly increased,construction land and cultivated increased to some extent.The largest reduction was the unutilized area,with a significant reduction in area,and a decrease in the area of woodland and water.With the acceleration of urbanization,population growth and rapid economic development,the cultivated land and construction land in the core area of the ebinurlake basin have been greatly increased,and the unused land and water areas have been greatly reduced.(6)In view of the wetland conservation and ecological environment renovation project of ebinur lake basin,this paper puts forward four Suggestions: first,the principle of sustainable development of social economy;Secondly strengthening regional land management,and promote the optimization of landscape pattern,formulate a long-term plan to protect plains again nature reserve,especially for protection of rivers into the lake,strengthen monitoring,control,management and repair;Finally,strengthen coordination and cooperation among various departments and improve relevant legislation. |
