This study starting from the forest management inventory for Suqian in 2009, make full use of "3S" technology to identify the total forest resources, structure, spatial distribution and forest cover ratio, etc, of Suqian. Through remote sensing interpretation factor, land type, small volume quadrat estimation, GPS positioning verification, investigate the border line of forest management unit, and in scope of management area, adjust (review) the management partition, the area of various land and various type of forest, status of forest growing stock, survey the ecological factors and geographical environment related to forest resources, establish forest resources information management system, analysis and evaluation for the forest resources dynamic changes trend of Suqian.Research show that:the total forest resources of Suqain have increased, forest coverage ratio has improved; regional distribution of forest resources is uneven; structure of forest species is adjusting; structure of forest age to be rational; the amount of poplar resources is big; reserves resources is rich, the total of accumulation is increasing, forest resources become a virtuous circle.In this study, the characteristics of forest resources is analyzed and evaluated, the following conclusion is achieved:1) the proportion of forest land is large, the development of forest is vast; 2) the differences of forest regional distribution is large, some area have great potential for afforestation; 3) the ratio of various forest species become more rational, consistent with requirements of the development of modern forestry; 4) the area of young forest is large, following forest resources is adequate; 5) plenty of poplar resources, have a good industry prospects; 6) ecological position is important, the proportion of forest is rational, ecological functions need to be improved.Based on the basic situation of forest resources, proposal to protect forest resources, provide a reference for sustainable use and management of forest resources of Suqian in future.
