植树造林

New China was founded at the beginning, we started a large-scale afforestation, but in contradiction with this large-scale deforestation is more.

新中国成立伊始，便开始了大规模的植树造林，但与此相矛盾的却是更大规模的毁林。

He said, after this many years of planting trees and building forests, Beijing has already greatly raised the rates of forest greening and forest coverage and also the per capita area of green land, but many places have merely been greened, while people have no way to enter and relax because there are no roads and absolutely no coordinated leisure facilities.

他说，经过这么多年的植树造林，北京不管是林木绿化率、森林覆盖率，还是人均绿地面积都已经大大提高了，但很多地方只是单纯的绿起来了，人却无法进去休闲，因为没有路，也没有任何配套的休闲设施。

Under the background of digital DEM of maor mountain area, and through the program of Avenue in Arcview, the result of potential ravine highly inosculates with the real ravine. With the comparison of potential ravine and real ravine, it can reflect the developing tendency of ravine in this area. Through positioning with GPS and investigation in this area, we can divide the potential ravine of this area into three forms, that is parallel ravine area steep ripe ravine area and evenness swamp area. It can provide scientific reference for forest management and tree planting, and it is a new theory to prevent soil and water loss, and carry through the ravine controlling by people.

在数字化生成的帽儿山地区DEM基础上，通过二次开发生成的潜在沟系，具有与现实沟系高度的吻合性，并通过与现实沟系的比较，能客观的反映出该地区沟系发生、发展的趋势，借助于GPS的定位及实际踏查研究，可将帽儿山地区的潜在沟系划分为平行沟系区、陡坡显沟区和平坦沼泽区三种类型，可为合理的森林经营和植树造林提供科学的借鉴，并为防止水土流失，进行沟系治理提供了新的理论依据。

To tackle the erosion problem,a large area of suitable mountains has been reforested.

与此同时，政府官员似乎也意识到了中国面临的环境威胁，比如建设三峡大坝的副作用。因此在疯狂地征用粮食耕地，而要求农民在光秃秃的山上植树造林，试图阻止土地沙化和洪水的发生。

Macrophanerophytes such as pine and cedar are more and occupie greater percentage to from bottom to top, which are affected by clime and geography and human avtivity. Because people pay more attention to Macrophanerophytes and less to shrub and herbge plants, ecology of the forest is unbalance and benefit is low.

在整个沉积物柱的孢粉组合中，松、杉等大型乔木始终占有很高的比例，而且越到上部比例越大，这除了受滇中地区气候地理因素的影响外，可能还有人为的原因，人们在保护森林资源和植树造林过程中往往只是注重了大型的乔木而忽视了灌木和草本植物，从而使森林生态失衡，生态效益低下。

Third, water, soil, plant trees to be maintained, it is necessary to use tree planting to curb soil erosion, afforestation must be, because the trees are as large as the crown of the root system, like giant hands firmly grasp the general soil.

第三，植树使水土得到保持，就要利用植树来抑制水土流失，所以必须要植树造林，因为树木有像树冠那样庞大的根系，能像巨手一般牢牢抓住土壤。

In the experi- ment and practice m the zhongwei North Main Canal of the Hetao Irrigation District, a cheap and quick functioned slope protection method of soil and grass mixture for tree planting has been searched for de- sign and construction of irrigation canal and drainage in the desert region.

河套灌区在中卫北干渠进行了试验，在沙漠建渠道，用人工和植物固沙，沙漠区排水沟道的设计则充分考虑水流冲刷，对沟道防坍塌摸索了一条花钱少、见效快的草上植柳护坡办法，并在灌区内植树造林以固沙。

China has committed to a target of 20% forest cover by 2010, and tree planting has been actively encouraged.

中国在大力鼓励植树造林，以期在2010年使森林覆盖率达到20%。
