煤炭部门每年因采煤要导致大面积耕地,村庄塌陷,电厂每年也要占用很多土地堆放废煤灰,不仅破坏了大量的耕地,而且也污染了环境。用废煤灰充填塌陷区复田,对电厂处理废煤灰,煤炭部门解决居民的迁村,耕地的恢复与环境保护,恢复矿区生态平衡均有重大意义。 柳树具有适应性强,繁殖容易,生长快等特性。它是煤矿塘材和矿柱的优良树种。尤其采煤塌陷区面积大,地势低洼,柳树更能发挥其生产潜力。因此,本试验通过对柳树育苗、造林生长规律的研究,以便为塌陷区复田育苗、造林提供理论依据和实践经验。
Coal mining sector each year to lead to large areas of arable land, villages collapsed, the power plant also occupy a lot of land every year piling ash, not only destroyed a lot of cultivated land, but also pollute the environment. Recycling of subsided areas with waste coal fines, the treatment of waste coal ash in power plants, the coal sector to solve the residents of the relocation of the village, the recovery of arable land and environmental protection, restoration of ecological balance are of great significance. Willow has adaptability, easy reproduction, fast growth and other characteristics. It is an excellent species of coal ponds and pillars. In particular, coal mining subsidence area is large, low-lying, willow to play its production potential. Therefore, this study through the Willow seedlings, afforestation growth law, so as to provide the foundation and practice experience of rehabilitating nursery and afforestation in the subsidence area.
