Study On Population Carrying Capacity For The State-owned Forest Region In Heilongjiang Province

The study on population carrying capacity in state-owned forest region is an important aspect for sustainable development of forestry. The concerned theories and methods about population and carrying capacity are used in this dissertation to illuminate the intension and extension about population carrying capacity in state-owned forest region, to analyze the status quo and to calculate the level of population carrying capacity in Heilongjiang forest industry zone. Combined the current circumstances of Heillongjiang forest industry zone, the dissertation puts forward the conclusion that the population carrying capacity in Heilongjiang forest industry zone is much lower than that of economic scale in existence, and educes the problems that overload of population causes the reduction of resource, depravation of environment, inconvenient of economy and lower living standard, expense of future interest, etc. Therefor these problems inevitably result in a marked drop in population carrying capacity. Through factors analysis about population carrying capacity in state-owned forest region, many main influencing factors (such as production and output capacity of forest resource, supply and demand situation of market, average income level of population in state-owned forest region, policy environment etc,) are obtained. Then this dissertation estimates that the level of population carrying capacity has the different changes in different phases and conditions, although its natural condition is established and fixed. So many effective measures should be adopted to develop forest population carrying capacity. These effective measures include: (1) to increase investment of forest tending by a reasonable support policy in forestry;(2) to expand forest area and improve forest quality by the scientific methods of forest tending;(3) to develop and exploit forest resource by the modern forest engineering and technology; (4) to raise the capacity and quantity of economy output of forest resource by the rational structure of industry and the effective scientific and technological content in forest products; (5) to increase residents income from non-wood forest products in forest region ,etc...
