摘要
论文综合土地适宜性评价与土地利用相匹配、各生态功能区空间格局导向性和高效生态农业发展目标的原则,提出了黄河三角洲土地资源优化配置方案。基于该方案,在GIS技术的支持下,对黄河三角洲土地资源进行优化配置研究。最后,针对"三网"绿化工程规划,对基于优化配置后的未绿化宜林牧用地进行立地条件分析和树种配置,全力打造黄河三角洲生态绿洲。
Utilizing land resources reasonably is a basic national policy and basic condition for social development in China. And it is important to the development of society and to the national e- conomy and people＇s livelihood. The Yellow River Delta abounds in natural land resources, but its ecological environment is fragile. The exploitation of the high-effect ecological economic zone has reached the level of national strategy on November 23, 2009. Based upon which, the paper puts forward the reasonable and comprehensive plan of land resource development and utilization, the division of agriculture land, construction land and ecological use land, and probes the management pattern of land use, and pushes the high-effect use of land resources. For this purpose, it is significant to study optimal allocation of land in view of ecology, in order to make best use of land resources in the Yellow River Delta （YRD,Dongying section）. The paper takes the YRD as the study area. By virtue of GIS technologies, in the viewpoint of ecology, optimal allocation scheme of land resource is constructed and applied to guild land resources adjustment based on the principles of land optimal allocation. The principles are struc- tured by combining land suitability evaluation results, land use status, spatial pattern guideline of ecological functional zones, with the target of high-efficiency ecological agriculture plan. Then according to the scheme, it is computed that the area amount is 2256 km2 of the land suitable for forest and weeds and without greening. At the same time, acted on the layout of the ＂Three Net- works Greening＂ （TNG） project, forestation site types are predigested and improved. Soil type, relief, salinity and groundwater levels are combined as main classification factors and irrigation conditions as a reference to sort site land into eight types. In this way, the land suitable for forest and grass is greened according to the planting patterns. Finally, by overlaying forestry site type map with TNG plan map, some suggestions and strategies are put forward and utilized to direct the TNG project. The ecological oasis of the Yellow River Delta will come into being.
