农田林网建设存在的问题林网总体规模减小,发展不均衡。通过对河北省南部平原县市农田林网现状的调查发现,目前,农田林网控制率大约在65%左右,较上世纪70年代下降20%,而且发展水平也很不均衡,好的县市在85%以上,差的地方不足40%,极个别的地方几乎没有形成林网,形成了上万亩、甚至近10万亩的空旷地。我国北方平原绿化达标的标准是要求农田林网控制率是
Existing problems in the construction of farmland forest network The overall size of forest network is reduced and the development is not balanced. According to the investigation of the status quo of farmland shelterbelts in Pingyuan County of southern Hebei Province, it is found that at present, the control rate of farmland shelterbelt is about 65%, down by 20% over the 1970s, and the development level is also very uneven. In more than 85%, poor places less than 40%, very few places almost no forest network formed, formed on the mu, or even nearly 10 acres of open land. China’s northern plains green standard is to require farmland forest network control rate is
