摘要:
分析了黄土丘陵区农业生产现状和存在的主要问题，指出广种薄收习惯是导致土地利用不合理，植被遭到破坏，进而水土流失加剧和生态环境恶化，农业生产力降低的根源。该地区生态农业建设的核心是改变广种薄收习惯，治理水土流失，不断调整优化土地利用和产业结构。依据土地资源状况提出目前阶段1234的土地利用结构模式。认为在占总土地面积20%的基本农田和果园，只要实行集约化经营就可实现较高的经济效益，70%的土地应为林草地。根据生态农业的基本原则和当前生产水平提出生态农业建设三个阶段的不同指标和适宜治理度，当前该地区主导产业的发展应以资源-结构-质量型模式为主。
Abstract:
The present situation and main problems of agriculture production in central hill region of Loess Plateau was analyzed and it was indicated that extensive cultivation habit caused non rational land utilization and vegetation destruction, then proceed to intensify water and soil losses, ecological environment worse off, agriculture productivity decrease.So the core of ecological agriculture construction in this region is: transforming extensive cultivation habit, controlling water and soil losses, revising and optimizing constantly land use and domain structure.According to land resources status, authors proposed 1234 land use mode and considered that higher economic benefit can be obtained by means of intensive farming on basic farmland plus orchard(20% of total land area), so 70% of land should be woodland and grassland.According to the basic principle and present produce level, the three stages and their target as well as suitable control degree were proposed.
