建设农田防护林,不仅能防御或减轻各种自然灾害,改善这一地区的小气候、水文、土壤和生物因素,同时林带也起到用材林、薪炭林、经济林、绿肥林和饲料林的作用,可以大大提高生物生产力(生物量) 和经济生产力,为人们提供多种多样产品和更适宜的生活环境,它是促进生态平衡的一项战略措施. 淮北属暖温带半湿润季风气候,常年降水量在700～950毫米,但年际变化很大,多者达1618毫米,少者仅441毫米(阜阳),并且全年雨量分配不均,60%以上集中在6～8月,1982年7月21～23日新汴河、濉河、奎河上游三天降雨竟达250～300
The construction of farmland shelterbelt can not only prevent or mitigate various natural disasters and improve the microclimate, hydrology, soil and biological factors in this area, but also play a role in timber forest, firewood forest, economic forest, green manure forest and feed forest in the same time. It is a strategic measure to promote ecological balance by improving biological productivity (biomass) and economic productivity, providing people with a variety of products and a more suitable living environment.Huaibei is a warm temperate semi-humid monsoon climate with annual precipitation of 700 ~ 950 millimeters, but varies greatly from year to year, with 1618 milliliters in most cases and 441 millimeters with less (Fuyang), with an uneven distribution of rainfall throughout the year, with more than 60% concentrated in June to August and July 21 to July 23, 1982 On the new Huanhe, Bahe, Kuihe upstream three days as much as 250 to 300 rain
