It is the concrete measures of carrying out the strategy of development of Western China in a large scale and the strategy of state forestry development to develop fast-growing and high-yield plantation.

With these years efforts,we have achieved splendid results in the construction of fast-growing and high-yield plantation in Jiangxi province,however,there are still many factors which affect their velocity and quality seriously.

The countermeasures of logging fast-growing and high-yielding plantation based on clean production were put forward.

Fast-growing and high-yielding plantation project has a long-term period,which requires a huge investment in amount,while the excepted return ratio of investment is relatively low.

Based on analyzing the situation of short-rotation fast-growing and high-yield eucalyptus forests within several years in Gutian County,countermeasures for developing the fast-growing and high-yield eucalyptus forests in Gutian County are posed,which gives references for developing fast-growing and high-yield forests smoothly and perfectly in Gutian County.

This assay studies the development of fast-growing and high-yield forest.

On basis of the analysis of the problems of development of Fast-growing and High-yielding forest in Jiujiang recent years,some countermeasures of forestry resources development have been put forward in this paper.

The problems of irrational structure,main management body vacancy, fund deficiency,low scientific and technological content and low stand quality exist in fast growing and high yielding forest base construction in north Fujian?Some analyses of present base situation are concluded in this paper,meanwhile,concrete countermeasures and measures are raised with regard to the base construction.
