进入七十年代以来,我省平原绿化有了很大发展。“六五”期末平原林木覆盖率提高到7％左右,其中32个(现已达40个)县(市)已经达到林业部颁平原绿化标准。平原绿化的发展改善了平原农区自然生态环境,并显示出较高的经济效益。目前,平原地区的立木蓄积量已达3457.4万立方米,占全省立木总蓄积量的72％。但是平原绿化在商品化生产崛起的今天,面临着新的挑战。为此,我们必须研究新的对策,以求得平原绿化事业的进一步发展。一、生态理论促进了平原绿化的发展
Since entering the seventies, our province has a great development of plains greening. At the end of the Sixth Five-Year Plan period, the coverage of plain woods has been raised to about 7%, of which 32 (now 40) counties (cities) have reached the Ministry of Forestry’s original plains greening standard. The development of plains and greening has improved the natural ecological environment of the plains and showed higher economic benefits. At present, the accumulation of stumpage in the plains has reached 34.574 million cubic meters, accounting for 72% of the total stumpage in the province. However, plains greening in the rise of commercial production today, facing new challenges. To this end, we must study new countermeasures in order to achieve the further development of plains afforestation. First, ecological theory has promoted the development of plains greening
