能源林是最近才出现的概念,旨在栽培速生树种,专用为燃料。鉴于当前不可能利用耕地栽培和净水灌溉,能源林建设主要有赖于利用边际土地(此种土地不够肥沃,耕种无利可图,非至农产价格高涨时不加利用──译注)和污水。为了使这个计划成功,必须在遗传学和农艺学方面进行深入研究,以提高有希望的高能树种的品质和生产能力。从技术上说,能源林就是栽培短期内就能收获的树种,专作为燃料。这种燃料 Energy forests are a concept that has emerged only recently, aiming to grow fast-growing tree species and to be used exclusively as fuel. In view of the current impossibility of using arable land for cultivation and irrigation of pure water, the construction of energy forests depends primarily on the use of marginal land (not fertile enough, unprofitable farming, non-utilization of agricultural inputs) and sewage . In order to make this plan a success, in-depth studies in genetics and agronomy must be conducted to improve the quality and productivity of promising high-energy tree species. Technically speaking, energy forests are species that can be harvested in the short term and are used exclusively as fuel. This fuel
