长城以南宁陇干旱半干旱黄土丘陵区草地生态农业模式研究

STUDY ON THE AGRO GRASSLAND ECOLOGICAL PATTERN IN ARID AND SEMI ARID HILLY AREA ON NING LONG LOESS PLATEAU IN THE SOUTH OF THE GREAT WALL

长城以南宁陇干旱半干旱黄土丘陵区无论其自然生态环境,还是农业生产体系均具有典型农牧交错、农牧结合的特征。本文在对该区自然生态和社会经济状况深入调查研究的基础上,结合作者近年所取得的研究结果,将研究地区划分为四个生态区、七个生态经济亚区。并就不同生态经济单元的综合特征和农业可持续发展途径进行了探讨。提出了土地- 植物- 动物“三位一体”草地生态农业不同的发展模式。
