Imperilment degree of black cutworm is very serious in both high altitude region as Dewu (1780 meters) and low altitude region as Lemin (1450 meters). The imperilment degree in two regions have no obvious differences. 4. The imperilment of second generation armyworm is very serious in both high altitude region of Dewu and low altitude of Lemen town.

The regularity, characteristic, and degree of pest imperilment of Dewu in Zhongshan district(middle-high altitude) and Lemin town in Panxian district (middle-low altitude) was researched in this thesis. And by analysing the similarities and differences of different pests in the two regions, this thesis bringing forward the control efficienticy from the views of production and ecology.

本文以在六盘水玉米生产中有代表性的钟山区德坞办事处和盘县乐民镇为代表，分别调查两地玉米主要害虫的发生规律、为害特点和为害程度，分析两地玉米主要害虫发生为害的异同，同时进行了药剂防治试验，并从生产全局及生态学的观点出发，提出了玉米害虫综合治理措施。

In 2000,the area below 400 meters was also watershed,mining sites and settlements,the proportion of both unutilized land below 400 meters and woodland between 400 meters and 800 meters raised a little,it showed that most woodland transform into the other types of land use in low altitude area,however,most unutilized land and the other types of land use transform into woodland in low and mediad altitude area,and the changes in woodland had metastatic trends in low and middle altitude area in the years from 1988 to 2000.The area proportion between 400 meters and 800 meters raised a lot in mining sites and settlements,the total distributed area on woodland had a trend of rising,while the distribution in pasture had a trend of decreasing.

在2000年，400m区域以下依然是水域和居民点及工矿用地，未利用地比例在400m以下有所上升而林地比例在400m～800m有所上升，表明在1994年至2000年间，低海拔地区许多林地转化为其他土地利用类型，而在中低海拔地区大量的未利用地和其他土地利用类型转化为林地，林地的变化有向中低海拔转移的趋势。2006年居民点及工矿用地在400m至800m区域面积比例增加，林地类型分布区域整体呈上升的趋势，草地分布区域呈下降的趋势。

鼎湖山土壤二氧化硅，锰含量随着海拔梯度的上升而下降，赤红壤含量高于黄壤；然而铁含量则随着海拔梯度的上升呈上升趋势，赤红壤含量低于黄壤，钙全量含量和磷含量也是赤红壤低于黄壤。（4）土壤Pb马尾松林含量最高，随着海拔梯度上升含量有下降趋势。

Comparison of the same Southwest monsoonal climate areas and the same study period with Dongge Cave and Kahf Defore Cave in δ18O values, the tufa core of δ18O in Huanglong is higher extent than these of Cave records, which altitude effect and different removal of moisture source regions maybe lead to extent difference in δ18O values; and we can draw a conclusion the tufa core records of Huanglong in the high altitude and middle latitude areas is more sensitive respond to climatic environmental changes than records of stalagmites in Dongge Cave and Kahf Defore Cave from the low altitude areas.

同属西南季风区、由于海拔效应和距离水汽来源远近不同等因素的影响，在同时段内黄龙钙华δ18O 的变化范围和变化幅度都比董歌洞和Kahf Defore 洞的δ18O记录要大，说明处于中纬度、高海拔的黄龙钙华相对于低海拔的董歌洞和Kahf Defore洞石笋对气候环境的响应可能更加敏感。
