摘  要:
利用四川省雅安市雨城区1995和2015年两次森林资源规划设计调查数据,分析了雨城区近20a森林资源的变化特征。结果表明:林地面积从1995年的5.46万hm~2增加到2015年的7.69万hm~2,增加了2.23万hm~2;森林覆盖率从43.50%增加到62.46%,增加了19.46个百分点。活立木蓄积从1995年的218.7万m~3增加到2015年的525.06万m~3,增加了306.3万m~3;林地生产力从36.97 m~3/hm~2增加到67.99 m~3/hm~2,增加了31.02m~3/hm~2。天然林保护和退耕还林工程的实施促进了森林面积、蓄积和森林覆盖率的增加。

摘  要:
Using the investigationdata of forest resources in 1995 and 2015,this paper analyzed the forest resources dynamic change of Yucheng District in recent20 years. The results showed that: from 1995 to 2015,the area of forest land increased from 54,600 hm~2 to 76,900 hm~2,increased by 22,300 hm~2; forest coverage rate increased from 43. 50% to 62. 46%,increased by 19. 46%; standing forest stock increased from 2. 187 million m3 to 5. 2506 million m~3,increased 3. 063 million m~3; forest productivity increased from 36. 97 m~3/hm~2 to 67. 99 m~3/hm~2,increased by 31. 02 m~3/hm~2. Natural Forest Protection Project and Converting Farmland into Forest Project has increased the forest area,volume and coverage rate.
