农牧交错带在持续发展战略中的特殊地位

The Special Role of the Borders Between Farming and Ranging Regions in the Sustainable Development Strategies

农牧交错带是指从我国西部牧区到东部农区，从干旱地区向湿润地区，以及从高原到平原、盆地的过渡地带。地处我国东部地区的风、水源头，具有防风固沙、涵养水分、净化江河、防止水土流失的特殊生态地位。拥有丰富的煤炭、石油、天然气和水力电能资源，是国民经济持续发展的能源基地。它的西北侧有辽阔的草原和大量家畜，东南侧紧靠我国的玉米生产地带。充分运用现代农牧产业技术将二者科学地结合起来，充分发挥农、牧、林三大系统的耦合效应，其效果可成数倍地提高。二十一世纪很可能成为继东南沿海之后，我国经济发展的第二条黄金地带。

The borders of farming and ranging regions are transition zones where ranging regions turn into farming regions, arid regions into wet regions, and plateu, plain into basin, wind and water unusally originate from these zones, which can break wind, conserve moisture, purify polluted water, prevent soil erosion, which can provide plenty of energy such as coal, oil, natural gas. They are the energy bases on which west-middle China great economic developments are based on- To the northwest of these regions,there are the best rangelands and a large number of livestocks, and maize production centre lie to southeast of them. If advanced animal husbadry technologies applied in these regions, economic efficiency will be doubled; there is no doubt that these regions will become the second prime zones for economic developments succeeding southeast China coastal areas in the 21st century.
