摘要
在浙江省淳安县新安江开发公司界首林场,建立森林生态研究站,经三年的观测研究,取得了许多有关界首马尾松林气候、水文生态效应方面的科学数据和信息。清楚地表明了千岛湖区马尾松林能通过温热因子调控,以影响微域气候条件:通过降低林内蒸发(林内仅为林外的36.8%)和径流(林内仅为降水量的0.25%),以增强水源涵养能力;通过截留大气中的营养化学元素(近650.0kg/ha·年)和积累森林枯落物(7.584t/ha·年),以提高土壤的肥力……等方面,均具有显著的功能和效益。
A temporary Forest Ecological Station was established at Jieshou Forest Farmof Xinanjiang Development Company, Chunan County, Zhejiang. After three years observationand research, a great deal of scientific data and information of the effects of climatic andhydrological ecology of Masson pine forest in the region of Thousand Islands Lake were obt-ained. The function and benefit of climatic and hydrological ecology of Masson pine forestshowed clearly that the forest can effect the microclimatic conditions by regulating the thermal-factors conserve the water rosource by decreasing of evaporation (the decrease of annualevaporation in the forest is 36.8% as compared with the non-forest land) and of run-off fromthe surface of the forest soil (in the forest the run-off is equal to 0.25% of annual rainfall);capture the nutritious chemical elements. from the air (nearly 650 kg/ha. yr) and accumulateforest litter (7.584 ton/ha. yr) to increase the fertility of the forest land, etc.
