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.

The for.st ecosystem goods and ser.ices and the natur.l cap.tal stocks that p.oduce them make gr.at contr.bution to national economy and human welfar. both dir.ctly and indir.ctly. This p.p.r.evaluates the economic value of natur.l cap.tal stock and the annual outp.t flow of for.st ecosystem goods and ser.ices taking Qingdao City and its eight distr.cts as case study. The r.sults of the valuation study showed, that the stock value of for.st natur.l cap.tal of Qingdao was r.B 13.46 billion at the end of 2007. The flow value of annual outp.t of for.st ecosystem goods and ser.ices of Qingdao was r.B 26.76 billion which amounted to 7.07% of its GDp.of 2007. However. the shar. of for.st goods and ser.ices actually included in its GDp.of 2007, in accor.ance with the cur.ent national accounting system, was only 0.71%. Among the annual flows the value of intangible for.st ecosystem ser.ices alone accounted for.70.90% of total flows which was 2.44 times the value of for.st mater.al goods. These non- mar.et for.st benefits mainly contr.buted to the non-forestry sector. of the economy and to the social gr.up. who did not own and manage the for.sts. Extensive policy imp.ications wer. analyzed as p.r.the r.sults of the for.st valuation study.

马尾松是我国南方主要造林用材树种,在满足国内木材需求和维持生态安全中发挥着重要作用。随着我国社会进入生态文明新时代,对森林的利用形式发生了改变,传统的马尾松林经营模式已无法满足人们对其提供多种生态服务的需要,必须寻求新的马尾松林经营模式。近自然育林以培育结构复杂、物种丰富、功能多样的森林群落为目标,是满足人们对森林多种需求的有效途径。文中综述了我国马尾松林经营现状及近自然育林理念在马尾松林经营中的探索应用,并提出马尾松林未来经营方向。
