摘要:造林过程中如采取不适当的营林措施会对环境保护起负面影响。为此世界银行贷款国家造林项目提出了对新造林地进行环境观测的要求。中国林业科学研究院亚热带林业实验中心在国外松科研推广项目的湿地松示范林内设置了以水土保持为主要目的的监测设施,观测工作于1992年...
According to requirement of the National Afforestation Project assisted by the World Bank, the soil erosion monitoring installations had been installed and observed on January 1 1992 in demonstration forest land of slash pine. The observation showed that lost amount of water and soil and nutrient was at maximum in the first year after planting and decreased with the increase of planting time. There were no significant difference between treatments with different measures. The range of runoff in both planting plot and non planting plot was 179 9~28 0t·hm -2 ·a -1 and the soil loss was 73 1~3 4kg·hm -2 ·a -1 in four years, which was lower than the permissible lost of national standard in these areas. The tree growth of slash pine exceeded the standard of high yield forest.It was proved that the dominant factor of influencing the soil and water losses was the disappearend and recovering of vegetation in a area. In the monitoring demonstration forest, the trees grew well so that the aim of cultivating forest and protecting environment was obtained.
