摘要: 本文对我国南海岸线上的"绿色长城"——粤西沿海防护林带的生态与经济效益作了总结分析,调查研究表明:30年来,这一海防林带抵御台风和防止风沙危害效果显著;农作物及林木产品经济效益增加。总的看,林带林产品收益只占林业总收益的1/4,而保护农田与环境的生态收益却占林业总收益的3/4。故作者认为:目前,不应过份强调生产林产品,只能适当进行更新采伐,以防历史上的风沙灾害重演。

Abstract: It is summerized that the coastal dune plantation in western Guangdong Province, since last three decades, is being played a desirable role on anti-typhoon and combatting the hazards of local dune movement and preventing seatide erosion, on protection of crop fields and on the increase of the economic result of farming produce and wood products. It is estimated that the income of wood products of the plantation belt occupies only 1/4, but the ecological benifit of the belt to protect the farmland and the environment occupies three fourths of the total incomes. The author considers that, at present, the production of wood products should not be emphazised and successional inter-felling should be properly made to stop the disasteres of wind and sand to return to the region.
