摘要
在阳江设点监测加勒比松林地水土流失状况。 4年的监测结果表明 :采伐后迹地采用除杂、炼山、挖大穴营造的加勒比松林 ,当年容易引起水土流失 ,其固体径流量和土壤养分流失量均显著大于无造林 (对照 )地 ;它们的年度差异达极显著水平 ,有随年度的增大而减小的趋势。
The condition of water and soil erosion in Caribbean pine land has been monitored and analyzed for 4 years. The results showed that slashing and burning disposal after felling easily led to water and soil erosion, water and soil erosion in the forest land which had been hole site preparation was more serious than that in non forest land in the first year.
