With the use of GIS technology and from an ecological point of view, an optimal allocation scheme of land resources is constructed and applied to guide the adjustment of land resources. Given this scheme, we have calculated that the area of land suitable for forest and shrubs without greening is 2256 km^2. Simultaneously, acting on the layout of the TNG project, afforestation site types are prepared and improved. Soil types, microrelief, salinity and underwater levels are combined as major classification factors and irrigation conditions as a reference to classify sites into eight types. In this way, land suitable for forest and grass is afforested given particular planting patterns. Finally, by overlaying this forestry site type map with the TNG plan map, some suggestions and strategies are proposed and used to direct the TNG project. An ecological oasis of the Yellow River Delta should be the result.展开更多

The results show that water pollution caused economic losses of about 541. 5814 million yuan in the Yellow River Delta in 2010; particulate matter caused health risk economic losses of 163. 1369 million yuan,and excess mortality economic losses of33. 4742 million yuan; noise pollution caused economic losses of 594. 2768 million yuan. The total losses reach approximately 2705. 198 million yuan,accounting for 0. 97% of the total GDP. After subtracting the total losses from the total regional GDP( 541. 58 billion yuan),the revised green GDP is about 536. 3127 billion yuan. Obviously,environmental pollution has a certain impact on the economic growth.The coordinated development of environment and economy can be achieved by adjusting the industrial structure,developing circular economy and so on.展开更多
