黑龙江西部退化草地的综合治理措施及其效益分析

COMPREHENSIVE HARNESSING MEASURES AND BENEFIT ANALYSIS OF THE DETERIORATING GRASSLAND IN THE WEST PART OF HEILONGJIANG PROVINCE

本文在总结和分析多年来治理退化草地所采取的林草间作、建立人工草地、松土补播、封育、喷灌、施肥等改良措施的基础上,根据改良效果计算了经济效益。结果表明,通过种草及多种改良措施能大幅度提高草地生产能力,经济效益和生态效益十分显著,其中以种草、围封、施肥等措施的复合处理效果最好。

With respect to the production potential and economic benefit of the grassland, the harnessing measures such as tree-grass intercropping, closed cultivation, spray irrigation and artificial grassland used in the pastseveral years for the deteriorating grassland are investigated in this paper. The production potential of the improved grassland is increased greatly. Economic and ecological benefits are significant. The result of the multiharnessing of several measures is best.
