main supports of the economy of Gannan Tibetan Autonomous Prefecture are traditional stockbreeding and agriculture. With a higher ratio of poverty-stricken population, this Prefecture sees rapid growth of population, which has intensified the conflicts between population and food, resource, and environment. Researches on issues concerning population and environment of Gannan Prefecture shall benefit the protection and construction of local habitats and the mitigation of local population pressure, and improve the neighboring ecological environment and people's living quality as well. As the guard to local habitats of Gannan Prefecture, grass vegetation plays a critical role in securing ecological health of neighboring areas.This paper summarizes preceding theoretic fruits got from researches on issues of population and environment. Based on social investigations and collection of related data and literature, this paper probes into the following issues one by one.Respective concepts of researches on population and environment are defined, while an analytic framework for issues of population and environment at Gannan Tibetan Autonomous Prefecture is presented. Based on such definition and presentation, this paper draws a summary on the theoretic foundation for the research of population and environment issues at Gannan Prefecture. Theories relating to researches on issues of population and environment at Gannan Prefecture are theory of optimum population, theory of demographic transition, theory of development and environment relationship, externality theory, theory of sustainable development, and scientific outlook on development.Revealed by investigations on history and current situation of natural resources and habitats at Gannan Prefecture, Gannan Prefecture enjoys abundant natural resources but severely damaged habitats. This Prefecture is strengthening ecological protection and construction. However, Gannan Tibetan Autonomous Prefecture is still suffering exasperated habitats. Meadows are victims of "three change" problems, forests are destroyed, water resource becomes insufficient increasingly, biodiversity reduced rapidly, and water and soil is being lost continuously. This paper studies the development status of population at Ganan Prefecture. Especially issues as population scale, population process, population structure, family panning, and population control are elaborated in detail. Generally population transition of Gannan Tibetan Autonomous Prefecture is at the second stage featuring high birthrate and low death rate. Population of this stage imposes the highest pressure on environment.At Gannan Tibetan Autonomous Prefecture, relationship between population and environment is strained, urgent, and lasting. Key population factors that impact habitats of Gannan Prefecture are:Too quick growth of population, higher ratio of poverty-stricken population, ecological migration, production style of the stockbreeding industry wherein a majority of local people labor in, and Gannan people's awareness of environment. Divided by matching mode and relationship of population, resource, and economy, Gannan Prefecture belongs to the first case of overload class, i.e., e>r>l, population-economy pressure is bigger than population-resource pressure, and these two types of capacities are overloaded.Sociological methods are used to cover questionnaires and case studies on environmental issues of Gannan Prefecture and review local residents'knowledge, understanding, and advice to environmental issues.This paper delivers countermeasures to build harmonic development of population, resource, and environment at Ganan Tibetan Autonomous Prefecture:To develop economy of Gannan for promoting population transition and environmental protection; intensify governmental interference and policies'coordination; realize sustainable development of population and environment; materialize policy of family planning and control population growth at Gannan Prefecture constantly; substantiate scientific outlook on development and further the healing management on habitats of Gannan Prefecture; implement National Ecological Environment Protection Program to speed environmental protection at Gannan Prefecture; and carry out environmental education to publicize awareness of environmental protection in Gannan people.
