Study On Forest Landscape Optimizing Scheme Of Linkou Forestry Bureau Based On GIS

The research based on GIS and forest ecosystem management theory and technology. With explicit target and underlie the forest resource characteristic analyse of Linkou Forestry Bureau, we plotted out several forest ecology resource hierarchies and management area to adjust the distribution of the forest resource of Linkou Forestry Bureau, and optimized the forest landscape structure. This accelerated the succession of lower natural secondary forest and some pure planted forest to Korean pine and broad-leaved climax forest community. This study made important basic research work for continuable management of forest resources.The forest resource characteristic of Linkou Forestry Bureau is: the stock ratio of Young, middle-aged, near mature and mature forest is 54:40:5:1, the ratio of near mature and mature forests is less and the ratio of young and middle-aged forests is mass; the percentage of pure forest plantation to total plantations area is 87.63%, this brings about the plant diseases and insect pests and the decline of fields fertility and forest function of water and soil holding and water conservative.Use the GIS database of Linkou Forest Bureau to fit Rechards equation, we calculated the parameters of each dominant tree, and workout the theoretical age-stock growth curve table of each dominant tree. The test precision is 97.27%, measures up industry standard.In order to protect the entironment of Linkou Forest Bureau, we plotted out 3 ecological resource layers, which are catchment area of Lianhua Lake and bank protection area of main rivers, protection area of railways and main roads, and landscape field of vision around residential area. Cutting in these areas is forbidden.After 50 years from our landscape planning, the landscape structure changed to 31% Larix gmelinii, 27% Pinus koraiensis, 11% broad-leaved trees, 11% Picea sp., 7% Abies sp., 4% Quercus sp., 3% Fraxinus mandshurica, 3% Populus tremuloides, 1% Juglans mandshurica, 1% Phellodendron amurense, 1% Pinus sylvestris var. from 27% Larix gmelinii,...
