| 中文摘要: |
| 陕北丘陵沟壑区退耕农田在发展林果草业上有显著优势,牧草具有很强的生态适应性。退耕农田种草在防止水土流失、发展畜牧业生产、促进退耕还林(草)和改善生态条件以及促进当地经济发展等方面有重要的生态作用,通过建立生态、经济、社会效益兼收并蓄的林草种群结构,推行保护性种植模式,合理规划沟域和调整农业生产结构,扩大种植规模和实行产业化发展等措施促进退耕农田的高效合理利用和开发。 |
| 英文摘要: |
| Returning farmland to forests or grassland in loess hilly regions of North Shaanxi plays an important role in natural resource use, water and soil conservation, agricultural sustainable development, forestry and grassland construction, and regional economy development. The main countermeasures for highly-efficient use and exploitation of returned farmland are suggested: setting up an optimal structure of forestry and grassland; introducing protective planting system; constituting rational valley programming and adjusting agricultural production structure; enlarging the planting scope of pasture and developing grass industrialization. |
