The sixth part: Studies on the dynamic changes of soil retention function value of ecosystem in YUYANG District. Utilized ERDAS8. 5 to interpret the remote sensing image and get LUCC data and vegetation information of YUYANG District. Utilized R2V5. 5 to digitize administrative map, topographic map, vegetation picture, soil distribution map and meteorological website map. Utilized ARCINFOR8. 3 to change every digitization layer to the same projection, to generate Tyson polygon, to structure DEM and do vector polygon overlay. Utilized ARC VIE W3. 3 to obtain the grid data topographic slope and slope length from DEM data of YUYANG District, and then, turned every coverage layer into grid layer and do grid polygon overlay to gain data about dynamic changes of value of soil retention of ecosystem in YUYANG District, at last, the author analyzed the features of the spatial-temporal changes and its reason.The seventh part: Studies on the dynamic changes of fixing drifting sand against wind function value of ecosystem in YUYANG District.

第六部分：榆阳区生态系统土壤保持功能价值动态变化研究；利用ERDAS8.5对遥感数据进行解译获得榆阳区土地利用数据和植被信息，利用R2V5.5数字化榆阳区政区图、地形图、植被图、土壤分布图及气象站点分布图，利用ARCINFOR8.3对各数字化图层进行投影转换、泰森多边形生成、DEM构建和叠加分析，利用ARCVIEW3.3从DEM数据中获取榆阳区的坡度、坡长面域数据，并将上述各图层格网化，然后通过栅格图层叠加分析和代数运算获取榆阳区生态系统土壤保持功能物质量和价值量时空动态变化数据，最后分析了其变化的时空特点及形成原因。
