Forestry Programming Planning In The Yellow River Delta Based On RS,GPS And GIS

The environment and development are two topics today. We more and more realized significance of Forestry to social economy. The leaders of Dongying municipality Shandong province, think much of developing Forestry in the Yellow River Delta. As a kind of monitoring method, Remote Sensing technology (RS), as a kind of position method, Global Positioning System (GPS), both were combined with Geographic Information System (GIS), which is a very useful tool for studying the Forestry Programming Planning in the Yellow River Delta. Under this background, the study on Forestry Programming Planning there through the technology of 3S can't only provide the foundation to "populus-paper plup" but also serve for the sustainable development of the Yellow River Delta.Under supports of 3S, multi-temporal Remote Sensing data, terrain data and hydrological data were applied to the study on the Forestry Programming Planning in the Yellow River Delta, which included the following main parts:(1) Study on soil salt content. The spatial Variability characters of two soil layers (30-40cm, 90-100cm) and the spatial correlation for soil ions in the Yellow River Delta was analyzed by geostatistical method. We analyzed the spatial distribution pattern of soil salt content by geostatistical functions of GIS. At the same time, the affected factors on soil salt content were studied. Above research results provide credible data for Forestry Programming Planning.(2) The forest land suitability in the Yellow River Delta. We calculated the weights of every appraisable factor by Analytic Hierarchy Process (AHP), and chose categorical standard by the integration index model based on the soil data, terrain data and hydrological data in the Yellow River Delta. The forest suitable level map was created with spatial analyst of GIS in the Yellow River Delta.(3) Discussion on salina forestation. Method of forestation was designed from the literatures about Salina forestation technologies according to the Yellow River Delta environment.(4) Salina forestry programming planning. According to the forest suitable level map and the situations in the Yellow River Delta, forestry programming unit was partitioned. Using the smallest program unit finished salina forestry programming planning in the Yellow River Delta.
