Analysis Of Landscape Pattern In Dongfang Of Hainan Province

Landscape pattern in a different landscape interaction as the main objective, and improve the ecological environment of the region. This thesis, Dongfang Hainan Province as study area, using the area of law of conservation of information, move the window and landscape stability evaluation model analysis of landscape pattern of Dongfang, Hainan Province, and propose appropriate landscape optimization and adjustment program and proposals for regional sustainable development. The results showed that the analysis showed that:1) Dongfang tree woodland and agricultural land as dominant landscape class, more widely distributed building land and other land-a disadvantage landscape class, the distribution is concentrated.2) Effect of particle size on the basis of the loss of precision analysis and area information available, Dongfang City, ecological landscape landscape of suitable particle size of 90m, particle effects analysis results can be used to select move the window, that is analyzed by size of (4n+1) times the window as an alternative measure, both guaranteed under the scale of the study area, as reflected in the range of ecological landscape information consistent with field observations, but also to ensure efficient operation when a computer for analysis.3) Based on moving window analysis available,2610m window scale for the analysis of Dongfang City in Hainan ecological landscape more reasonable analysis scales, this scale landscape change index floating relatively smooth, the status quo can better reflect the landscape pattern in the study area.4) Based on the difference between the analysis of landscape stability space available, Dongfang City spatial distribution of landscape stability, results showed that the overall ecological environment of Dongfang City in good condition, stable region where the landscape is mainly distributed in the southwest portion of the region is mainly large trees woodland, natural broadleaved mixed forest types based; moderately stable mainly distributed in Tuo Xing Dongfang City Reservoir dam around the reservoir and the big wide, the region mainly arbor forest, agricultural land and waters cross distribution; Fair stable area is mainly distributed in the Thanksgiving river, near the South River and Daan reservoir in the region mainly dominated woodland and agricultural land, waters scattered; generally unstable region mainly towns and villages, mainly in the area of construction land and other land mainly affected the ecological environment of human activities, significant changes; the main distribution area is very unstable region four more towns, new Longzhen, Baoban towns and urban Dongfang City, the region's main building and other land uses, ecological environmental subjected to high intensity artificial transformation severely damaged.5) Taken returning farmland to lakes, afforestation and other measures for Dongfang City. To adjust the proportion of the regional landscape construction land, agricultural land and other land, improve landscape quality woodland and mangrove forest, optimization Dongfang City landscape structure, improve the ecological environment and promote ecological and economic benefits shared growth and achieve sustainable development Dongfang City.
