逻辑图:
P1verview
1、研究数据引出话题(present data)
2、研究的三个结果:(abundant,reduced-increased-and thus increased,counterproductive)
P2:呈现两方观点
1、intensified controversies
2、View1(the view that...is widely held and common cited)
3、View2(alternative view)
4、作者观点:data are lacking
P3:展现实验数据论证观点
1、present data
2、采用biscuit fire的原因
3、study的过程(used and sampled)
P4:实验结果
1、结果1(natural conifer regeneration → suggesting active reforestation )
2、结果2(reduced,due to,result in)
3、结果3(significantly increased, in terms of, would likely exhibit )
P5:作者观点
1、观点1(incongruent)
2、解释观点1
3、观点2(承接观点1):underscore
4、观点3(转折):however
5、解释观点3(leaving,result in)
6、观点4(thus)
P6:总结
1、our data show that
2、In addition
Simple story
P1verview
1、研究数据引出话题(present data):话题关于conifer regeneration & fuel loads
2、研究的三个结果:
结果1--after fire, natural conifer regeneration was abundant
结果2--postfire logging reduced median regeneration density→increased woody fuels→increased short-term fire risk
结果3-postfire logging is counterproductive to the goals of forest regeneration & fuel reduction
P2:呈现两方观点
1、intensified controversies
2、View1:postfire logging reduced fire risk & forests will not adequately regenerate without intervention
3、View2: postfire is harmful to long-term forest development
4、作者观点:data are lacking
P3:展现实验数据论证观点
1、present data
2、采用biscuit fire的原因
3、study的过程(used and sampled)
P4:实验结果
1、结果1
natural conifer regeneration is abundant
suggesting active reforestation may be unnecessary
2、结果2
Postfire logging reduced generation
If conduct postfire logging,replanting can not result in net gain in early conifer establishment
3、结果3
Postfire logging increased fuel loads
Reburning the trees→increase rates of fire spread, fireline intensity, and soil heating impacts
P5:作者观点
1、观点1: postfire logging 不能降低燃料负荷
2、解释观点1
3、观点2(承接观点1):降低短期火灾需要随后的fuel reduction treatments
4、观点3(转折):however,implementing fuel reduction treatments is problematic
5、解释观点3: mechanical removal贵;burning is the most feasible method→导致不好的影响
6、观点4(thus):the lowest fire risk strategy is to leave the dead trees standing
P6:总结
1、Postfire logging不能实现森林再生和降低燃料的目标
In addition:森林再生不一定都是危机 |
