生态林业在发展农垦质量效益农业中的地位与作用

为了科学评价生态林业在发展农垦质量效益农业中的地位和作用，总结出服务于大农业的生态林业发展对策，通过分类设立重点农场进行调查，数据对比和分析得出：由于农田防护林的庇护使小麦平均增产15.4%，大豆平均增产14.7%；营造水源涵养林和水土保持林按一个周期计算，投入产出比达1:12；用同样的耕地发展苗圃的利润比农业高十倍；沙化瘠薄耕地退耕还林可转亏为盈；通过兴办家庭林场，发展生态经济型林业，实现农场增效、职工增收。并针对完善生态林业提出了四大工程和发展对策。通过对比、分析得出生态林业体系建设为发展质量效益农业奠定了基础，并使林业产业逐渐成为新的经济增长点，在质量效益农业、安置就业、培育新的经济增长点等方面发挥着越来越重要的作用。

Discussion on the Position and Functions of Ecological Agriculture in Developing the Agriculture of Quality and Benefit Type

In order to evaluated the status and role of eco-forest on quality and efficiency of agriculture in States Farms, aggregate development strategy of eco-forest for overall agriculture, we investigated the key farms, the data from comparison and analysis led the following results: the protection of the farmland shelterbelt could increase the average yield of wheat by about 15.4%, increase the average yield of soybean by about 14.7%; the input-output ratio of planting water conservation forest and soil and water conservation forest could reach 1:12 in one construction cycle; the profit of nursery is ten times of farmland for the same area; returning desertification infertile farmland to forest can turn loss to profit situation; farms increase efficiency and workers increase income through construct family forest farm and develop eco-economic forest. We proposed four projects and developing strategy to improve eco-forest. By way of comparison and analysis, we get conclusion that construct eco-forest system laid the foundation for developing quality and efficiency agriculture, make forestry industry gradually become a new economic growth point, and becomes an increasingly important role in quality and efficiency agriculture, increasing employment ,and foster new economic growth points.
