摘要:
根据调查的精度要求,在1∶25 000地形图公里网交叉点随机确定起点后,按样地的间距依次进行调查。利用GPS对样地进行定位,采用角规控制检尺方法进行蓄积量调查,分析间隔期林地及林木资源的变化特点。结果表明:有林地面积增加79 826.9 hm2,增幅达8.82%;疏林地面积减少4 921.7 hm2,降低了69.75%;灌木林地面积减少14 985.6 hm2,降低了7.78%;未成林造林地面积增加65 450.9 hm2,增幅达202.44%;无立木林地面积增加18 679.1 hm2,增幅达121.92%;宜林地面积减少48 565.2 hm2,减幅达53.91%。苗圃地面积减少442.8 hm2,减幅达42.94%;辅助生产林地面积增加47.3 hm2,增幅达52.61%。活立木蓄积量增加增加15 191 860 m3,增幅达37.61%。有林地蓄积量增加15 184 910 m3,净增率38.53%。疏林地蓄积量减少35 870 m3,降低了58.90%;四旁树蓄积量减少52 980 m3;散生木蓄积量增加83 980 m3。
Abstract:
The study arranged survey plots at intervals of 2.0 km×2.0 km after the starting point was randomly determined in the 1∶25 000 topographic map in 2008 and 2015. The boundary of city, county, town, village and ownership were used as administrative boundaries of forest resource inventory provided by the Civil Affairs Department. The change characteristics of forest land and forest resources at intervals were analyzed by comparing the forest resources survey data with GPS sample positioning, angle gauge control for measuring volume survey. The findings showed that forest land increased by 79 826.9 hm2, 8.82%; The woodland decreased by 4 921.7 hm2, 69.75%; shrub land decreased by 14 985.6 hm2, 7.78%; immature forest plantations increased by 65 450.9 hm2, 202.44%; area with no tree increased by 18 679.1 hm2, 121.92%; suitable land for forest decreased by 48 565.2 hm2, 53.91%; nursery land decreased by 442.8 hm2, 42.94%; auxiliary production forest land increased by 47.3 hm2, 52.61%; standing timber volume increase by 15 191 860 m3 ,37.61%; forest volume increased 15 184 910 m3, 38.53%; open forest land volume decreased by 35 870 m3, 58.90%; ′Four sides′ tree volume decreased by 52 980 m3. Scattered trees volume increased from 82 750 m3 to 166 730 m3, an increase of 83 980 m3.
