摘要
利用裕安区2004年与2013年森林资源二类调查数据,分析了森林资源现状特点及十年间的变化。结果表明：全区林地比重较高,占土地总面积的36.31%,林地主要分布在南部低山和中部丘陵岗地地区,北部平原区相对较少;林种、龄组结构比较合理,树种结构有所改善。2004~2013年10年间林地面积、活立木蓄积、森林覆盖率和林木绿化率均实现了增长。裕安区实施生态公益林建设工程、森林增长工程、森林长廊工程取得显著成效,使森林资源快速增长,生态环境安全得到改善。
This paper analyzed the percent characteristics and developing changes of forest resources in Yu＇an district according to the 2nd-class inventory data of years in 2004 and 2013.The results showed that percentage of the region＇s forest land was higher,accounting for 36.31% of the total land area.The distribution of forest land was uneven.Forest land mainly distributed in low mountains located in the south and hilly region in the middle part.Forest resources were poor in the northern plain.The forest categories and age structure of forest were more reasonable and plant species slightly improved.The woodland area,forest volume of stumpages,the percentage of forest cover and greening rate achieved growth during 2004-2013.There was a rapid growth of forest resources and environmental security was significantly improved in Yu＇an district with the implementation of ecological forest construction,forest growth projects,forest corridor project.
