Analysis Of Cultivated Land Landscape Pattern And Its Influencing Factors In Chemingyu Township

Cultivated land is one of the important ways for the use of land resources,and it is an important basic resource for human survival and development.Cultivated land is related to China's food security and is an important factor affecting China's social stability.In this paper,Chemingyu Township of Zhongyang County is selected as the research area.Based on the actual data of cultivated land use obtained from the actual investigation into the village,mathematical statistics methods are used to analyze the current area and distribution of cultivated land in the study area,and combined with the principles of landscape ecology,Fragstats4.2 software was used to analyze the spatial pattern of cultivated landscaping landscape.Finally,ArcGIS10.1 software was used to select terrain,residential areas and roads,and the influence of the spatial distribution of cultivated land was discussed.Research indicates:(1)There is a large difference in the distribution of cultivated land among the administrative villages in Chemingyu Township.The farmland in this township is mainly concentrated in the administrative villages of Fengwei and Hedi,and the number of cultivated land distributed in the administrative village of Chemingyu is the smallest,and the per capita cultivated area of the administrative village is lower than the per capita cultivated land of the township.(2)Among the cultivated land landscapes in the administrative villages of Chemingyu Township,the arable land landscape of Fengwei Administrative Village is the main type,with a large patch type area and a high degree of landscape dominance;the average area of patches of arable land landscape in the administrative village of Chemingyu Village is the smallest,its arable land landscape is less dominant.From the patch shape of the cultivated land landscapein each administrative village,the edge length index of cultivated land landscape in Fengwei administrative village in each administrative village is the largest;at the same time,the landscape of cultivated land in Fengwei administrative village is greatly affected by human activities,and its patch shape is relatively rule.The heterogeneity of cultivated land landscape in Chemingyu Township is weak,among which the cultivated land landscape in Fengwei Administrative Village is spatially concentrated and its spatial connectivity is high;However,the connectivity of the cultivated land landscape in the administrative village of Chemingyu is low,and it is scattered in space.(3)The spatial distribution of cultivated land in Chemingyu Township is greatly influenced by the terrain,residential areas and roads.The terrain is mainly affected by elevation,slope and aspect.From the elevation point of view,the cultivated land in the township is mainly distributed at an elevation of 1137.77-1646.68 m.From the slope point of view,the cultivated lands of the six administrative villages are mainly distributed on slopes?25°;in the slopes of >25°,there are few arable lands.From the perspective of slope,the distribution of cultivated land in the township is different in different slopes.The cultivated land is concentrated on sunny slopes,semi-sunny slopes,and semi-shade slopes.The distribution on cultivated slopes is relatively small.From the impact of residential sites and roads on the spatial distribution of cultivated land,the spatial distribution of cultivated land has a certain negative correlation with the distance from the nearest residential sites and roads.With the increase in distance from the nearest residential sites and roads,the distribution of cultivated land is affected.In general,there is a decreasing trend.
