Forest Vegetation Landscape Pattern Based On GIS And RS Technology Changes

Forest vegetation landscape landscape ecosystem resources are extremely important components of forest ecosystems and the ecological environment of the entire regulation, plays a very important role in improving forest vegetation landscape pattern configuration is the basis for the rationalization of sustainable forest development. This paper studies the southern mountains for nearly a decade2003-2012Jinan space distribution of forest vegetation and landscape pattern changes. The main application of both2003and2012the southern mountains of remote sensing images, the establishment of the southern mountain landscape forest vegetation classification system through data processing. Landscape classification system information analysis temporal evolution of forest vegetation in the southern mountains, the simultaneous analysis of landscape pattern between these southern mountains for nearly a decade. On the southern mountain forest vegetation resources into classified study the evolution of its spatial and temporal variation and landscape pattern. Changes by RS and GIS technology to the southern mountain forest vegetation landscape pattern landscape resources research, monitoring dynamic changes in forest vegetation resources, to understand the process of succession in southern mountainous forest ecological environment, grasp the changes in the natural and socio-economic environment in the region, thus the future of the southern mountain forest vegetation in Jinan City and other areas to provide a scientific basis for the protection and development and learning.The main outcomes of the study conclusions obtained are:1.Through two periods south of Jinan City (hereinafter referred to as the southern mountain) forest vegetation remote sensing image processing, including remote sensing image acquisition, remote sensing image stitching, projection conversion, geometric correction, image cropping finally resolved by the amount of man-machine interactive Translated, the establishment of remote sensing image interpretation signs, establishment of forest vegetation in the southern mountains classification system, and the establishment of forest vegetation in the southern mountainous landscape classification system.2.Establishment of forest vegetation in the southern mountains classification system: According to the southern mountainous landscape resource types are divided into:(. Platycladus orientalis, Cotinus coggygria Scop) arborvitae (Platycladus orientalis), arborvitae, sumac, black pine (Pinus thunbergii), grassland slope, broadleaf forest, shrub grassland, forest, unused land, construction land, farmland, water. In this article, the study of forest vegetation landscape resource classification system arborvitae (Platycladus orientalis), arborvitae, sumac (Platycladus orientalis, Cotinus coggygria Scop.), Black pine (Pinus thunbergii) structural unity of these three species classified as broadleaf mixed landscape; the slope shrub grassland and grassland landscape classified as shrub grassland landscape; rest were forest landscape landscape, farmland landscape, a total of five broad-leaved forest landscape.3. Through the southern mountain forest vegetation temporal evolution of the analysis, the distribution of forest vegetation in the southern mountains and on the evolution of trends over time in space:in time, change1.2%overall area of forest vegetation in the southern mountains, but inside the forest vegetation undergoing tremendous succession, mutual conversion between the various forest cover a large area; spatial structure of forest vegetation in forest as the base (matrix), its most widely distributed, dominance max. Because large natural environmental conditions Jinan southern mountain range complex, forest vegetation in the study of spatial and temporal distribution of the southern mountains, taken in accordance with sub-regional study of soil types, north of the town of Zhong Gong, Crouching Tiger Mountain Reservoir and Dasha is Cambrian and Ordovician carbonate distribution area, south of the area of carbonate-granitic gneiss mixed soil types. From south to north as the research areas A and B, respectively. Presents changes in the structure of the forest is also space.4.Through the southern mountains of GIS data in2003and2012to establish the remote sensing images, perform southern mountain forest vegetation landscape pattern Jinan dynamics. The following conclusions:changes in landscape structure mainly for scrub grass, weeds and other natural or semi-natural sloping landscape degradation; forest landscape, farmland landscape patch area increased, the number of plaques increased fragmentation improve to become the dominant landscape types; needle The total number of broad-leaved mixed forest landscape patches showing a decreasing trend, the growth of plaque area, plaque showing a trend of polymerization; broadleaf forest landscape plaque area, have increased the total number of patches, the fragmentation also increased. Forest landscape to become the region’s base (matrix), is the most widely distributed range, the maximum connectivity, the biggest advantage of the plaque.
