The effect of the natural enemies were assessed according to the analysis, which revealed that the parasitoids played more significant role than the predators, and that Citrostichus phyllocnistoides which had the closest synchrony and sympatry with citrus leafminer P.citrella, should be considered as dominant natural enemy, and be protected and utilized to control the citrus leafminer. Wide niche and distribution as Orius sauteri has, its narrow overlap showed the less close sympatry and synchrony as well as impossibility to control the prey.

寄生性天敌群子强于捕食性天敌群子，表明在自然环境中寄生性天敌群子对桔潜蛾的控制作用强；捕食性天敌小花蝽Orius sauteri虽然食谱生态位宽，但生态位重叠却小，说明这种天敌尽管分布广泛，可在时间和空间上没能有效"跟随"害虫的发生，对害虫控制作用不大；寄生性天敌短腹桔啮小蜂Citrostichus phyllocnistoides与桔潜蛾在时间上的同步性和空间上的同域性均优于其它天敌，为优势天敌，应加以保护和利用。

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。

If this teaching is being impelled it has the function of giving the teachers a safe, convenient, economical outdoor teaching area and increases the mentors teaching materials. To the students it has the benefits of developing the attitude of cherishing and respecting life and to understand the characteristic of animals and plants. The anxiety however comes from the lack of educational teaching materials (55%), natural resources' lack of professional maintenance (53%), lack of funds (45%) and lack of relative knowledge (44%). The conclusion are that the government can conduct studies relative to the knowledge of Ecological engineering method or publish periodicals in order to increase the teachers' (50%) chance of getting in touch with knowledge of this field and let the supplier, middle man, acceptant of the education system to bring into full play of their abilities by providing them with more supports.

此一教学如加以推动，对教师而言是具有「可提供一个方便、安全、经济的户外教学场域」和「可增加教师的教学资源」等较重要的功能；对学生而言，则具有「可养成爱惜与尊重生命的态度」和「可让学生从实物中了解动、植物生态特性」等效益；但较担心的是教学教材资源（55％）、自然资源缺乏专业维护（53％）、经费（45％）及相关知识（44％）等的不足；因此，政府机关除了可以多办理有关生态工法知识的研习或发行刊物，以增加教师（50％）对这方面知识的接触机会外，在其他各方面亦应该提供更多的协助，让教育系统供给者、中介者及接受者都能发挥最大的功效。

This paper attempts to compare the images of China in Hong Kong literature and Macau literature from the aspects on politics, economics and ecololgy, in order to confirm the interdependent logical relationship among literary field and other social fields, and to exposit the discourse differences and potential factors of imaging China between the fields of Hong Kong and Macau literature.

Concludedly, it is pointed out that geotectonic is deeply influencing the erosion rule and is the decisive factor of desertification and lack of water in Huanghe River Valley in Shaanxi Province.(5) Based on the Theory of Dissipative Structure and the Hypothesis of Wavy Mosaic Structure, the coupling relation between eco-environment and geotectonics is theoretically discussed, and the main points are: i Degree of the order of eco-environment is higher in tectonic wave-dense belt than in tectonic wave-scatted belt.
