水土流失是当前严重的公害之一,防治水土流失是我国重大的决策。福建省水土流失面积约占全省总土地面积的十分之一。一些原来林木生长茂密的地方,由于“左”的路线干扰,对林业的破坏时间长,掠夺性强,致使林草生长能力锐减,山地表土裸露面积达20～40％,有的还出现细沟侵蚀。单纯通过封禁措施治理水土流失是难以奏效的,特别是在农村生物能源紧缺的地方,往往无法坚持而终告失败。我们根据农业系统的规律,把开源和节能相结合,可以使封禁治理达到较为理想的效果,把水土流失的控制,生态平衡的建立,群众的生活需要,生物能源的控制和节约等密切地结合起来,作为一个系统综合治理。三年来,我们在这个系统上进行一些尝
Soil and water loss is one of the most serious public hazards nowadays. Prevention and control of soil and water loss is a major decision of our country. The area of soil erosion in Fujian Province accounts for about one-tenth of the total land area in the province. Some of the original densely populated areas of trees, because of the “left” route interference, the destruction of the forestry for a long time, predatory, resulting in sharp decline in the growth capacity of forest and grass, mountain topsoil bare area of 20 to 40%, and some also appeared thin Groove erosion. Simply controlling the soil and water loss through the embargo measures will be ineffective, especially in places where the shortage of bioenergy in rural areas often fails to persist and eventually fails. Combining open-source and energy-saving based on the laws of the agricultural system, we can achieve a more satisfactory closure effect by closely integrating the control of soil and water loss, the establishment of ecological balance, the needs of the masses, the control and conservation of bio-energy, etc. Up, as a system of integrated governance. In the past three years, we have experimented with this system
