2005年是“十五”的最后一年,首都绿化传来喜讯:“十五”期间,全市累计造林197万亩,是“九五”的2倍,封山育林184．9万亩,飞播造林59．3万亩,全市林地总面积达到了1580万亩。北京1．64万平方公里的国土,已经一半以上被绿色所覆盖。前些年,曾经听到有人埋怨“年年栽树不见树”。不知不觉间,这句话已经从耳边消失了。怨言没了的另一面是树真的多了。“十五”期间,北京绿化造林步伐加快,森林资源总量迅速增长,绿化大工程带动大发展、大变化,绿化精品工程纷呈,机制和体制创新、实现了林业跨越式发展。说“树”还得用“数”来说。与“九五”末相比,林木绿化率由41．9％提高到50．5％,森林覆盖率由30．65％提高到35．47％; 活立木蓄积量由1428万立方米增加到1521．3万立方米;城市绿化覆盖率由36％提高到42％,城市人均绿地由35平方米提高到46平方米。据测算,全市森林资源的生态服务价值达3107亿元。 During the last year of “the Tenth Five-year Plan” in 2005, the good news came from the greening of the capital: During the “Tenth Five-year Plan” period, the total afforestation of the city was 1.97 million mu, twice that of the “Ninth Five-Year Plan”, 1,849,000 mu of afforestation and afforestation .3 million mu, the city’s total area of ​​15.8 million mu of woodland. More than half of Beijing’s 16,400 square kilometers of land is covered by green. A few years ago, I heard people complain about “trees are not seen every year.” Unconsciously, this sentence has disappeared from the ear. The other side of complaining is that trees are much more. During the “Tenth Five-year Plan” period, the pace of afforestation and afforestation in Beijing accelerated and the total amount of forest resources increased rapidly. Large afforestation projects led to great development and major changes, and green afforestation projects featured numerous innovations in mechanisms and systems to achieve a leapfrog development in forestry. Say “tree” still have to use “number” for it. Compared with the end of the “Ninth Five-Year Plan”, the afforestation rate of forest trees increased from 41.9% to 50.5% and the forest coverage rate increased from 30.65% to 35.47%; the stock volume of live trees increased from 14.28 million cubic meters to 15.213 million cubic meters; urban greening coverage increased from 36% to 42%, urban per capita green space from 35 square meters to 46 square meters. It is estimated that the city’s ecological service value of forest resources reached 310.7 billion yuan.
