Some conclusions from the study on human driving factor are:(1) the human activity is much more active factor to the process of desertification which mainly incarnates on the changes of the landuse fashion (from traditional rangeland 100 years ago come to interlacing agro-pastoral region) and enhance of landuse intensity (over-cultivation, over-grassing and over-fuel collection);(2) the natural vegetation had been destroyed suicidally by human activities that had accelerated to the development desertification.

在人为驱动力的分析中，得到以下一些初步的结论：（1）人类活动是本地区沙漠化过程中更加活跃的驱动因子，体现在土地利用方式的转变（从传统的牧业草原到今日的农牧交错区）和强度的增加（过度开垦、放牧、樵采等）；（2）由此对自然植被群落毁灭性的破坏，加速沙漠化的进程。

This papers is divided into six chapters and seeks to combine heritage buildings and the concept of modern information. The author make a preliminary analysis and research about historical information constitution of heritage buildings. On this basis, we strive to present a new vision to examine and discuss about the conservation of heritage buildings. Throughout the course of the study and exposition, we make Chinese ancient buildings of timbered structure as its main target, and combine with many examples about ancient buildings of timbered structure in Shanxi Province. In this papers, the author combine the abstract information with the concrete buildings closely, and hope to provide a new way of thinking for the study of heritage buildings through this way.

Starting with the elevation of underground water resources and a safe level of mining through variable system theory, this paper analyzes the conditions of underground water resources based on the well-studied determination method of determining the two hydrographical coefficients: rainfall infiltration replenishment rate and irrigation replenishment rate. Then considering irrigation, rainfall, drainage and other related factors, a mathematical model is set up for the calculation of underground water storage,exploitation on water regulation. After analyzing the adaptability of molepipe drainage, an underground water table regulation is given out.

论文从灌区的地下水资源及其可开采量评价分析方面入手，在对两个主要的水文地质参数即降雨入渗补给系数、灌溉入渗补给系数确定方法研究的基础上，对灌区的地下水资源状况进行分析，依据灌区的灌溉、降雨、排水条件及各种现状因素，建立了地下水资源量计算的数学模型，西安理工大学工程硕士专业学位论文计算得到青铜峡灌区地下水的最大补给量和可开采量；另外对在开发利用地下水资源过程中的地下水位的调控进行了初步的探讨，在银北灌区开展对暗管排水调控地下水位的试验研究。
