我国山区占土地总面积的2/3，具有人类活动强度大，生态环境脆弱的特点。在快速的城市化过程中，我国山区乡村人口发生了显著变化，呈现出一些显著特点：山区乡村人口显著减少；年龄结构变化明显；人口空间布局发生巨大变化。那么，山区人口变化如何影响植被恢复，这种影响程度有多大呢？本申请拟通过农户调查和野外调查，选择太行山区作为研究区域，分析山区人口压力变化对植被状况的影响机理。在此基础上，建立山区植被状况变化的解释框架，选择解释变量。在随机选择900个样本（每个样本面积为64km²），栅格化所有解释与被解释变量，在控制自然要素（如气温、降水、海拔、坡度、坡向）影响的基础上，运用多元回归模型，定量表达2000-2015年人口压力变化对山区植被恢复的影响。

Mountainous areas in China account for two-thirds of the total land area; they are characterized by high human activity intensities and fragile ecological environments. During the rapid urbanization process, rural population in mountainous areas are experiencing some significant changes: the rapid decrease in population, remarkable changes in age structure, and re-distribution of rural population in mountainous areas. Then, how do changes in population in mountain areas affect vegetation conditions , and to what extent these will changes influence vegetation conditions? This study will firstly discuss the changes in population and their impacts on vegetation conditions in Taihang mountainous areas, using the household survey data. Based on this, this study will establish the explanatory framework for vegetation conditions, and the explanatory indexes will be selected. Then, we will carry out rasterization on all explanatory variables, including temperature, precipitation, gradient slope, elevation, and population pressure. Through the random selection of 900 sample areas (each sample measured about 64 square kilometers), the contribution of population pressure on vegetation restoration will be quantitatively measured by the multiple regression model, on the basis of eliminating the influences of natural and landform factors (such as temperature, precipitation, gradient slope, elevation) on vegetation conditions.
