The area set aside for the new community, however, has been neatly reforested. 然而,开发商对为新社区留出的区域重新进行了精心的绿化。
They managed to clear two-thirds of the newly reforested site before being evicted. 他们在被强行驱逐之前,试图对那里三分之二新种植的林区进行了砍伐。
The soil qualities of six land use types ( natural forestland, grassland, shrubs land, secondary forestland, cultivated land and reforested land) were compared using two quantitative methods: the integrated soil quality index ( QI) and soil deterioration index ( DI). 采用了综合土壤质量指数法(QI)与土壤退化指数法(DI)两种定量研究方法。
The content of soil available P and rapidly available K in subsoil in these two reforested patterns are lower than in farmland. 两种退耕还林模式表层土壤速效P和速效K含量均低于农耕地。
Based on eight years 'data, this paper studies the effect of cut over on the hydrological functions of soil in an ecosystem and focuses on the biological regulation and restoration effects of trees on soil hydrological functions after the second generation Chinese fir stand is reforested. 以连续8a的测定数据,探讨了皆伐对生态系统土壤水文学功能的影响,并着重研究了营造第二代杉木人工林后林木对土壤水文学功能的生物调节和恢复状况。
After the seedlings cultured indoor on the flat filter pad have been cultivated for 3 months in autumn and winter, they can be accounted for more than 70% at height up to 10 cm, and can be relatively early reforested uphill. 以室内用平盘垫滤纸作发芽床培育的苗木,在秋冬季培育3个月,苗高达10cm以上的占70%以上,可以比较早出圃上山造林。
