Research On Agricultural Landscape Development In Low Mountain Areas Based On Site Analysis

Low mountain area is widely distributed in rural areas in China.Due to the complex development of terrain conditions,the development of low mountain areas has become an important strategy to alleviate the shortage of land resources.This research is based on the theory of landscape ecology and comprehensive theoretical knowledge and methods such as landscape taxonomy,terrain analysis,botany,and mathematical statistics.Through the investigation and the actual situation of the field landscape of the sea of flowers pastoral complex in swopring,the three quantitative indices that can directly reflect the distribution characteristics of the landscape types are used.They are introduced to associate with the terrain factors: Landscape Distribution Index,Land Use Composite Index,and Green Coverage Index.Analysis explores the distribution of landscape types in the study area.In order to provide a theoretical basis and scientific guidance for the landscape planning and construction of the rural industrial integration development,it also takes the foundation for advancement of scientific and rational development for the advancement of research and development in low mountain areas.Through this study,the following results are obtained:(1)The change of land use index at different elevation levels first increased and then decreased,reflecting that the study area is not highly utilized in the low altitude area and high altitude area,and the degree of utilization is highest in the middle altitude area of the area and there is irrationality.The change of land use index at different slope levels increased first and then decreased,and the degree of utilization in the gentle slope and slope areas was relatively low.The changes in the grade index of the land use index are the highest in the sunny slope area and are significantly affected by human activities.(2)With the increase of elevation and slope,the green coverage index is gradually reduced.In high altitude and steep slope areas,it is not suitable for the growth of plants.Most hilltop areas exist in the form of wasteland.Ecological effects,visual effects,and production of vegetation landscapes are terrible.With the transition of the slope direction from shady to sunny,the green coverage index gradually increased,and the degree of utilization of sunny slopes was relatively high.(3)Low-altitude areas mainly include natural reservation land landscapes,farmland landscapes,and cultivated land landscapes.High-altitude areas mainly included grassland landscapes and forest landscapes.Gentle slopes and slopes mainly include farmland landscapes,grassland landscapes,forest landscapes,and residential landscapes.Steep slopes are dominated by forest landscapes.The landscape types are widely distributed and distributed evenly in the semi-sunny and semi-shady slope areas.(4)Regional land resources with high green coverage index in low-altitude areas,gentle slopes but belonging to more appropriate development have not been reasonably applied.High-altitude,steep slopes area are dominated by ecological landscapes,with high green coverage index and a low level of land use.There is a small amount of production and life landscapes.The landscape types in the semi-sunny and semi-shady areas are distributed more and the differences are smaller.According to the characteristics of the existing site,the following suggestions are proposed for the landscape layout: to promote the integrity of the landscape structure and enhance the richness of the industrial structure;to coordinate the rationality of the regional landscape and promote the high efficiency of land use;to carry out three-dimensional layout and strengthen the overall planning.
