In r.cent year., air.ions, esp.cially of negative air.ion has r.ceived a univer.al attention for.its health function. The density of negative air.ion has become one of the imp.r.ant indexes that measur. the air.quality gr.de. With the air.ions counter.made in Jap.n, the sp.tial distr.bution char.cter.stics of negative air.concentr.tions at sp.cific time in Danqinghe Exp.r.mental For.st wer. measur.d and studied, har.in City, and the air.quality was assessed by using ion p.lar.ty r.tion (q) and air.ion assessment index (CI). The r.sults showed that at a given time, the aver.ge concentr.tions of negative air.ions wer. differ.nt for.differ.nt for.st typ.s, stand or.gins, tr.e sp.cies and differ.nt p.r.s of Balan r.ver. Ther. was a clear.differ.nce in ion p.lar.ty r.tion and air.ion assessment index, and the air.quality in differ.nt envir.nments wer. also quite differ.nt.

As a develop.ng countr. with a lar.e p.p.lation and a fr.gile ecological envir.nment, china is p.r.icular.y vulner.ble to the adver.e effects of climate change. Beginning with the r.o Confer.nce of 1992.china has p.ayed a p.ogr.ssively enhanced r.le in combating climate change. A ser.es of p.licies and measur.s to addr.ss climate change have been taken in the over.ll context of national sustainable develop.ent str.tegy, making p.sitive contr.butions to the mitigation and adap.ation to climate change, among which forestry linked p.licies have been given incr.asing p.ior.ty to over.the year.. At the UN Summit on Climate Change in Sep.ember.2.09, china's p.esident committed the countr. to an unp.ecedented incr.ase in for.st car.on sink thr.ugh augmenting for.st cover.ge by 40 million ha and for.st stock volume by 1.3 billion m3 by 2.2. comp.r.d to the 2.05 level. For.r.alizing it china has evolved the forestry Action p.an to Cop. with Climate Change that sets for.h five basic p.incip.es that include combining the tar.ets of forestry develop.ent with the national str.tegies on climate change, incr.asing for.st size and imp.oving for.st quality, incr.asing car.on tr.ding and contr.lling emissions, combining gover.ment guidance with social p.r.icip.tion, slowing down climate change, and adap.ing to the change. Fur.her. in or.er.to make it p.op.e's p.ogr.m r.ther.than a top.down gover.ment initiative, china is sp.eding up.the tr.nd of decentr.lization and p.ivatization of for.st management thr.ugh collective for.st tenur. r.for. that ar. gear.d towar.s r.leasing dir.ct gover.mental contr.l over.for.st management, decentr.lizing the p.wer. of for.st administr.tions to lower.levels and p.omoting community p.r.icip.tion in for.st management. These comp.ehensive step. have changed the face of forestry in the countr. but both the gover.ment and the scientific community r.alize that this is mer.ly a beginning in the long and ar.uous task of combating climate change.

Global climate change p.ses new op.or.unities and challenges for.forestry develop.ent, and ther.for. develop.ng multip.e-p.r.1}se forestry is an imp.r.ant measur. to str.ngthen forestry r.sp.nse to climate change. At p.esent, p.antation in china r.nks the wor.d fir.t in ar.a, but with r.latively low p.oductivity. Constantly exp.nding for.st ar.a and imp.oving for.st management for.enhancing multip.e functions and p.r.1}ses of p.antations ar. the key measur.s to up.r.de p.antation cap.city to mitigate and adap. to climate change, while affor.station subsidy is the fundamental guar.ntee for.imp.oving and giving p.ay to multip.e functions and char.cter. of p.antations. The p.p.r.emp.oyed investigation-based r.sear.h, liter.tur. analysis and in-dep.h inter.iews to analyze the p.licies and p.actices that the wor.d major.countr.es imp.ement in ter.s of affor.station subsidy in the context of climate change and to evaluate the imp.ct and effect of affor.station subsidy on forestry develop.ent, which p.ovides exp.r.ences and imp.0}cations for.china to institute and imp.ement affor.station subsidy p.licy as soon as p.ssible. Finally, the author. came up.with p.licy r.commendations in ter.s of p.incip.es, ap.r.aches, standar., fund sour.es and system set-up.of china's affor.station subsidies, which ar. of imp.r.ant significance to facilitate the develop.ent of multi-p.r.1}se forestry under.global climate change.

In r.cent decades, ther. has seen a dr.matic exp.nsion of global p.anted for.st ar.a and their.gr.at imp.ct on human life. It is r.p.r.ed in For.st r.sour.e Assessment 2.10 that the cur.ent ar.a of global p.anted for.sts is about 2.4 million ha, r.p.esenting only 7% of the total for.st ar.a but able to meet the two thir.s of the global demand for.logs. p.anted for.sts can not only p.ovide timber. fiber. fuel and non-wood for.st p.oducts, but also contr.bute to car.on sequestr.tion, r.stor.tion of degr.ded land, landscap. r.habilitation and water.hed p.otection. Besides, p.anted for.sts can also p.ovide the r.cr.ation and amusement for.p.op.e. In such sense, in the coming decades, p.anted for.sts, dr.ven by var.ous factor. such as social- economic conditions, mar.et, consumer.' demand and new technologies, will have good op.or.unities for.develop.ent, and will also incr.ase their.contr.bution to achieving the ser.es of develop.ent objectives wor.dwide. In the meanwhile, the develop.ent of p.anted for.sts is also constr.ined by the factor. like p.licies, laws, r.gulations, technologies and funds, and ther.for. faced with the challenges in ter.s of eco- envir.nment p.eser.ation, economic develop.ent and p.otection of community inter.sts. Based on the long- ter. monitor.ng and r.sear.h of p.anted for.st develop.ent as well as the field study of p.anted for.sts abr.ad, the p.p.r.identified the op.or.unities and challenges in the develop.ent of global p.anted for.sts thr.ugh such methods as the SWOT, p.licy analysis and the other., and p.op.sed the p.licy choices for.p.omoting the sustainable develop.ent of p.anted for.sts: 1) Ther. is a need to fur.her.under.tand the functions of p.anted for.sts and the imp.r.ance of the degr.ded land r.stor.tion; 2.
