| Yellow river top inside visit the region is a whole world soil erosion the most seriously of one of the regions, realize the basic improvement of the ecosystem environment society can keep on developing with economy, and must make developments of good water and soil conservation ecosystem, and economize with protect water resources. This text rely on the item in yellow river water and soil conservation ecosystem engineering Zhengzhou mang mountain ecosystem park. This text analyzes 3 S technique the application is in the domestic and international research present condition that the water and soil conservation item program to design and development trend, bring up to study the contents and technique route; according to Digital Elevation Model( DEM), Remote Sensing ( TM, IKNOS or QUICKBIRDS), land to make use of the present condition diagram, combination open country to investigate, Make the yellow river water and soil conservation ecosystem engineering Zhengzhou Mang mountain ecosystem park item area the soil to erode the type and strength to distribute figure .At the same time, born slope of DEM diagram, aspect the direction diagram and land make use of the present condition and TM image to add, establish the GIS database. According to the land resources proper evaluation standard, established the land construction to adjust the database. Basis GSI terrace, divide the line out the scenery park the area, ecosystem landscape the wood to take, efficiently area of economic wood orchard is with the sword ditch, ten boundaries, fly the dragon crest the small river valley etc. six to manage the unit, and according to the item area the DEM study 4 kinds two type areas to synthesize to manage to install the mode. This text return point to item prevention and cure the measure, technique guarantee, organize management, engineering investment, economic society etc. the aspect proceeds can line argument. Item developments that point out the problem need the further quest solution. |
