Aiming at the ecological environmental deterioration of bashang , from 2002years to3 ~ 5months of 2003 years . sand - transporting quantity of land cover types were on - the - spot moinitoring in gale seaon , comparing the productivity of the main crops . improving environment and developing economy are compositively considered for applying returning cultivated to woodland and grassland to supply the base of theory and technology . the main results as following : 1 observing the sand transporting quantity of artificial grassland , stubble land and cultivate land . indicates that when wind speed is higher ( 8 . 0m / s ) , the sand transporting quantity of artificial grassland of 200cm reduces 35 . 5 % in average more than that of cultivate land , 34 . 5 % sand - transporting quantity than that of stubble land . no distinct difference between stubble land and cultivate land . and when wind speed is lower ( = 5 . 0m / s ) , the sand - transporting quantity of coverage is no distinct difference according to the analysis of variance 从改善环境和发展经济两方面综合考虑,为实施坝上地区“一退双还”提供了理论与技术依据。主要研究结果如下: 1对人工草地、作物留茬地及耕翻地的输沙量观测表明:劲风( 8 . 0m s )下,人工草地比对照耕翻地输沙量在200cm高度内平均降低了35 . 5 ,比作物留茬地平均降低了34 . 5 ;作物留茬地输沙量与耕翻地差异不显著;微风( 5 . 0m s )下,不同地表覆被类型对输沙量的影响差异不显著。
This paper expounded the consideration on researching and developing the new technical model in hilly drainage area during the process of agro - industrial structure adjustment , its characters of energy and material recycles , with the emphasis on introducting the efficiency of three renovation techniques in hilly area of northern fuzhou , i . e . construction of artificial grassland and feeding goats in rotation , qualified forage for pisciculture use , and ecosystimatical resilience of hilly orchard and improvement of its productivity 摘要阐述了在南方山地小流域农业产业结构调整中配套技术模式的研发思路及能量物质循环特点,重点论述山地人工草场的建设及山羊分区轮牧、优质牧草渔业产业化利用和低产山地果园生态恢复与生产力提升等三项创新性技术在福州北峰山地小流域实施的成效。
