On the basis of analysis of remote sensing image and DEM, and by combining with the cluster analysis of the main factors to the ecological environment, the division and evaluation of ecological environment in Jiangxi province have been done in this paper according to the heterogeneity among landscapes and the similarity of interior landscapes with the principle and method of landscape ecology. All of this provides the objective basis for Jiangxi province government to make a long term planning on the construction of ecological economy, to effectively solve the problems of ecological environment and to make the decisions on the development of social economy and protection of the ecological environment.
Taking SPOT and TM fused imagery as remote sensing information source, water and soil loss on the 1:50 000 has been investigated in Laogaochuan area of Gushanchuan river basin. This paper analyzed the main factors affect water and soil Loss of small river basin, pointed out that RS and GIS integration is a developing tendency for speed investigation of Water and Soil Loss in small river basin.
The essential types of altered rock related to Au mineralization in Wulashan, Maihanshan and Sunitezuoqi and the remote sensing methods to extract them are discussed in this paper. Some image processing methods are applied for extracting the altered information from TM data, such as Ratio, principal component and image classification etc. Field geological survey affirms a excellent concordance between image altered zone and gold mineralization-altered zone, and two large alteration zones are found by remote sensing process.
Based on the practical application of remote sensing techniques in the archaeological process, the major work and research topics on the archaeological process in Henan province are discussed in this paper. And one set method on the remote sensing-archaeology is established.
By means of GIS and remote sensing technique, the changes and evolvements characteristics of foreshore and deep channels of Lingding bay in Pearl River Estuary are analyzed. The change reasons and consequences are also illustrated. Basing this, it reminds us of standardizing the development behavior to the coastal area in favor of the long-term development of Pearl River Delta from the sustainable development high-points of coastal area.
Urban green land cover is an important part of urban landscape and performs a very important function in urban system. The traditional method for investigating urban green land cover is manual work and there is a lot of shortcoming and deficiency. This paper introduces a new method that using RS and GIS technology to investigate urban green land cover. We can use the data information in GIS that obtained using this method to analyze distribution of urban green land cover. Of course, the information can also help government to plan and manage green land.
In this paper, the cultivated land quality was evaluated. By multi-object plan model, the different cultivated land quality area were calculated. Space optimal disposition of cultivated land was completed based on tools of Arc/Info and MapInfo in computer.
This paper introduces the system for extracting and mapping of city green space based on aerial remote sensing data, including the method of city green space extraction, green space statistics, accuracy analysis and transformation from vector to raster. Aerial remote sensing data of East China Normal University is used to examine the system, the result showed that the system can quickly figure out the distribution and amount of green space, and the accuracy reaches over 85 percent.
