广东省基于连续清查资料的森林资源动态变化研究

Research on Dynamic Changes of Forest Resources in Guangdong Province Based on the Continuous Forest Inventory Data

根据1983～2007年森林资源连续清查6期数据，从资源数量、结果、质量、地理分布等四方面分析研究广东省森林资源的动态变化情况和原因。结果表明：全省林地面积、森林面积、林分蓄积和林分生物量呈增加趋势；中幼林和用材林仍是构成森林资源的主体，但阔叶林逐渐成为优势森林类型，生态林比重明显提高；虽然林地生产力在逐渐提高，但森林质量仍处于较低水平；全省森林资源分布仍呈现北部资源多、南部资源少、东西两翼沿海较平均的格局。

The dynamic changes of forest resources in Guangdong province and its causes were analyzed and studied from four respects of forest resources quantity, results, qualify and geographical distribution based on six periods continuous forest inventory data from 1983 to 2007. The results showed that forest land area, forest are- a, forest volume and biomass had increased, broad-leaf forest gradually turned to be dominant forest while middleaged and young forest were still the main part of forest resources now, and the portion of ecological forest would dra- matically increased. Although forest land productivity had been gradually growing, the forest quality was still low. It also indicated that more forest resources distributed in northern Guangdong than in the southern part, and the dis- tribution was much evener in east and west coast of Guangdong province.
