随着社会的进步和科技的发展,人类改造世界和利用自然的能力在不断加强。随着能源开采业和矿物勘探技术的发展,能源开采业和能源加工业的规模也越来越大,随之而来的还有矿物资源和化石燃料的大量消耗和环境污染。而环境污染日趋严重,使生态环境遭到严重破坏,甚至影响食物链的正常循环,威胁到人类的生存环境。因此,实施退耕还林的做法势在必行。基于此,从退耕还林工程的经济效应和生态效应出发,进行相关研究,以期为退耕还林工程提供帮助。
With the progress of society and the development of science and technology, the ability of mankind to transform the world and make use of it has been constantly strengthened. With the development of energy extraction and mineral exploration technologies, the energy extraction industry and the energy processing industry are also getting larger and larger, with the massive consumption of mineral resources and fossil fuels and environmental pollution. The increasingly serious environmental pollution, the ecological environment has been severely damaged, and even affect the normal circulation of the food chain, threatening the living environment of mankind. Therefore, the implementation of the policy of returning farmland to forestry is imperative. Based on this, starting from the economic and ecological effects of the conversion of cropland to forest project, relevant researches are carried out to provide help for the project of returning farmland to forestland.
