江西地处亚热带,气候温和,雨量充沛,山地面积辽阔,土壤深厚肥沃,对林木生长非常适宜,广大林区群众又有经营林业的经验。天时、地利、人和,发展林业十分有利。但是,过去由于“左”的思想影响,造林树种强求单一化(现在全省针叶树种占了总造林数的4/5),由于杉木等针叶树不能起到“自我施肥”的作用,而阔叶树种砍得多,造的少,地力得不到补充,病虫害严重,破坏了生态平衡,大大降低了“天然水库”“绿色屏障”“天然制氧”和“吸尘、滤毒、消音、灭菌”的作用。强调集中连片是对的,但没考虑适地适树和混交(本来要求是荒山造林,但也有的实际上是毁林造林),加上管理粗放,以及虚报造林面积,森林保存率低。据统计,建国以来,历年造林6000多万亩,而实际保存面积只有2100万亩(包括640万亩油茶林),保存率只占了30%。从过去历年造林数字来讲是一个高速度,据此迄今江西早应该绿化了。但由于成活率低,乱砍滥伐严重,不少地方还是满目荒山,水土流失严重。本来原先山上有树有草,但由于年年如此的“造林”,砍了烧,烧了挖,折腾来折腾去,植被被破坏,沃土被冲走,留下的只是石砾,不用说在上面造林,就是寸草也难生。 Jiangxi is located in the subtropical zone with mild climate, abundant rainfall, vast mountainous area and rich and fertile soil, which is very suitable for the growth of trees. The majority of forest area people have the experience of running forestry. The weather, geography, people and development of forestry is very favorable. However, in the past, due to the influence of the “leftist” ideology, afforestation species were strived for simplification (now the province’s conifers account for 4/5 of the total number of afforestation). Since conifers such as fir can not play a role of “self-fertilization,” broadleaf species Cut more, make less, the groundwork can not be supplemented, pests and diseases are serious, undermining the ecological balance, greatly reducing the “natural reservoir” “green barrier” “natural oxygen” and “vacuuming, filtration, silencing, sterilization ”The role. Emphasizing that conciliation is right does not take into account the appropriate allocation of trees and mixing (what was originally required to be barren hills afforestation, but some are in fact afforestation), coupled with extensive management and false afforestation, low forest conservation. According to statistics, since the founding of the People’s Republic, there have been more than 6 million mu of afforestation in previous years, while the actual preserved area is only 21 million mu (including 640 mu of Camellia oleifera). The preservation rate only accounts for 30%. From the past years of afforestation figures in terms of a high speed, so far so far Jiangxi should green. However, due to the low survival rate and serious deforestation, many places are still deprived of natural resources and soil erosion is serious. Originally, there were trees and grass in the mountains, but because of so many “afforestation” every year, they cut down their burns, burned them and toss them to toss them. The vegetation was destroyed and the fertile soil was washed away leaving only gravel. Needless to say, The above afforestation, that is, inch grass is also hard to live.
