林业生态建设中林业技术推广发展探讨林业产业的发展与林业生态建设的关系中国林业沿处在较低层次的发展阶段,森林资源增长缓慢与社会对林业日益增长的多种需求之间的矛盾成为现阶段林业的主要矛盾,生态需求成为社会对林业的主要需求,生态建设是林业建设的首要任务。本文就我国林业生态建设的现状及存在的问题进行分析;就林业产业的发展与林业生态建设的问题进行探讨。thedevelopmentofchina'sforestryisinthelowerlayeralongthephase,theslowgrowthofforestresourcesandthesocialdemandforforestgrowingavarietyofcontradictionbetweenthecontradictionbecomethemaincurrentforestry,ecologicaldemandbecamethemaindemandofforestrysociety,ecologicalconstructionistheprimarytaskofforestryconstruction.inthispaper,thepresentsituationofecologicalconstructionofforestryinchinaandtheanalysisofexistingproblems;asfarasthedevelopmentofforestryindustryandforestryecologicalconstructionwerediscussed.一、我国的林业生态建设直接影响林业产业的快速发展a,ourcountry'sforestryecologyconstructiondirectlyaffectstherapiddevelopmentofforestryindustry世纪之交的1998年,一场持续百天的全国性特大洪水,冲毁了无数良田、家园,洪峰频率之密、洪水流量之大、流域范围之广,百年罕见。全国共有29个省(区、市)遭受了不同程度的洪涝灾害,受灾2.3亿人,死亡人数3000人,各地估报的直接经济损失2484亿元。新世纪的第一个春天,我国北方地区连续发生10余次扬沙、浮尘和沙尘暴天气,造成部分地区机场关闭、交通中断,其频率之高、来势之猛、影响范围之大,不断刷新新中国成立以来的沙尘暴和沙尘灾害纪录。2008年初我国南方大面积的冰雪灾害,叫人不得不联想气候变化的影响和危害。attheturnofthecenturyin1998,anationwidefloodinglas第1页共10页tonehundreddays,countlessfertileland,homes,wasdestroyedbythefloodfrequencyofdense,big,wideriverbasinofthescopeofthefloodflow,rareinonehundred.atotalof29provinces(area,city)suffereddifferentdegreesoffloods,theaffected230millionpeople,thedeathtollof3000people,aroundfordirecteconomiclossof248.4billionyuan.thefirstspringofthenewcentury,thecontinuousoccurredinnorthchinamorethan10timesflyingsand,dustandsandstormweather,causingpartsofairportsanddisruptedtraffic,itsfrequencyishigh,withfierce,influencescopeoflarge,constantlyrefreshedsincethefoundingoftheduststormsanddustdisasteronrecord.largeareasofsnowandicedisasterinearly2008,thesouthofchina,peoplehavetolenovo,theeffectsofclimatechangeanddamage.大洪水的背后是植被破坏、水土流失;沙尘暴的背后是沙漠化、荒漠化;气候变化背后是气候变暖,极端天气增加和自然灾害的频发。事实上,中国的生态危机远不止此,当前全世界普遍存在的沙漠化、水土流失、干旱缺水、洪涝灾害、物种灭绝、温室效应加剧等六大生态危机,每七一样都与森林的植被破坏息息相关。新中国成立后的近半个世纪的时间里,由于国家经济建设的需要,以木材生产为主一直是中国林业的首要任务。中国林业的状况产出多于投入,中国生态的状况破坏大于治理,总体形势十分严峻。thefloodisbehindvegetationdamage,soilandwaterloss;sandstormisbehinddesertification,desertification;behindclimatechange,climatewarming,extremeweatherandfrequentnaturaldisasters.infact,china'secologicalcrisisismuchmorethanthis,thecurrentwidespreadallovertheworlddesertification,soilerosion,drought,floods,speciesextinction,thegreenhouseeffectintensifyingecologicalcrisis,andsoonsixbigeverysevenasiscloselyrelatedtoforestvegetationdestruction.nearlyhalfacenturyafterthefoundingofnewchina,asaresultoftheneedofnationaleconomicconstruction第2页共10页,mainlywoodproductionhasalwaysbeenthepriorityofchina'sfor...
