| The investigation area is located in Jingouling forest farm, Wangqing forestry bureau, Jilin province, which is one of representative over-logged forest areas in Northeastern China. Classification of forest landscape for the natural forest of this area is by remote sensing. On the basis of classification result together with local landscape situation, forest landscape planning principles and methods were put forward. The geography information system (GIS) technique was used in forest landscape programs. The author discussed the theoretical and application technique of forest landscape planning. Main research contents are as follows:The works include classifying and analyzing of spatial structure of forest landscape. Classification of forest landscape is based on data of multi-spectrum remote sensing of Landsat TM and terrestrial inventory. ERDAS images and MapInfo are used as technical supporting systems for data processing. Supervised classification of remote-sensing image supported by terrestrial sampling plots and associated with inventory data of forest management is used in the study. As a result, distribution map of forest landscape of the study area and its spatial structure analysis and evaluation were produced. These results served as useful information for further planning and planning of forest landscape development in study region.The works include planning of forest landscape and the development of its assistant system. First, the principle and method of forest landscape planning are put forward. On the basis of classifying of forest landscape and analyzing of spatial structure together with local landscape situation and planning target, considering landscape ecology basic principles, forest landscape planning principle and method for this area are put forward. Second, the author completed forest landscape planning, using Mapbasic, the advanced programming language of Mapinfo, established an aid-system of forest landscape planning. We applied this system on Jingouling forest farm and formed a new method of forest landscape planning with quickness and precise to realize its complicated planning process.Making use of classification by remote-sensing image may better carry through quick classification and appraise of spatial structure of region. Planning principles put forwardadapt the forest landscape planning of Jingouling forest farm, and can well develop the social, ecological and economic benefits. The result can be used as the local medium-long term planning of forestry development, and the reference of practice for forest farm .The finished technique system can be used for the forest landscape planning of the natural forest in northeast of China. The assistant system established on MapBasic language of the forest landscape planning can realize the forest landscape planning according to the landscape planning method, which is an effective tool with quickness and precise for forest landscape planning. |
