In this research, periodical and localized observations and measurements and ecological evaluation have been made on the moisture content, nutrient and gravels content of soil, formation of plant community, annual output of plants and their relative climatic conditions for eight types of southern slopes of mountainous areas. It is considered that the main barrier to vegetative rehabilitation on the southern slope of mountainous area is water, and that the moisture content of soil in mountainous areas over 800m in altitude is apparently better than that under 800m in altitude, but still cannot meet the requirements of large amount of water consumption of Chinese pine and locust trees. Hence, different ways should be taken for vegetative rehabilitation of southern slopes of mountainous areas at different altitudes. Amodel of forecast has been developed using quantitative analysis for the southern slopes of mountainous areas in Chengde district. It has been found that the major factors contributing to the net annual production of plants are in the following order, effective moisture content of soil, altitudes and thickness of soil layer. Various ways of vegetative rehabilitation are proposed accordingly. %U https://www.plant-ecology.com/EN/abstract/article_4023.shtml
