一、调查目的飞播造林是在无林地区摸拟天然更新的一种大规模机械化造林方式,具有速度快,成本低,投资少和省劳力等特点。在人口稀少,交通不便,劳力不足的边远山区更是一种有效的造林方式。建国以来,省先后在我州组织过四次飞播造林,对绿化成片荒山,加速林业发展起到了积极作用。特别以1986年的飞播面积最大、播区最多、战线最长、规模最大、成效也更为显著。为进一步总结经验,掌握规律,把今后的飞播工作做得更好,根据省、州安排,我所承担了红河州1986年飞播造林成效的调查与评定工作。从1986年9月开始收集资料,10月下旬进行试点,11月2日至12月30日开展了外业调查,随后进行了资料的分析、整理和汇总工作。
I. Purpose of the Survey Aerial seeding afforestation is a large-scale mechanized afforestation method that simulates natural regeneration in non-forest areas. It has the characteristics of fast speed, low cost, low investment and labor efficiency. In the remote mountainous areas, which are sparsely populated, inaccessible and labor-intensive, they are more effective afforestation methods. Since the founding of the People’s Republic of China, the province has successively organized aerial sowing and afforestation in our state four times and has played a positive role in afforestation into barren hills and accelerated forestry development. In particular, the area of aerial broadcasting was the largest in 1986 with the largest number of broadcasting areas, the longest front line, the largest scale and the more remarkable results. In order to further summarize the experience, master the law, the future of the airborne work to do better, according to provincial and state arrangements, I assumed the Honghe Prefecture in 1986, the effectiveness of aerial seeding investigation and assessment work. From September 1986 began to collect information, pilot in late October, November 2 to December 30 to conduct a survey of the field, followed by data analysis, collation and summary of the work.
