摘要
通过对黄土丘陵区草地的生态功能与经济功能的分析,认为草地建设是黄土丘陵区生态与经济建设的切入点,而水分是黄土丘陵区生态及经济建设的限制因子,维持黄土丘陵区水分平衡不仅是生态建设及经济发展的关键环节,而且是退耕还林(草)后的农业生产所必需的。并提出黄土丘陵区基于水分平衡的草地建设策略。
The ecological and economical functions of pasture in loess plateau were analyzed. Pasture establishment was considered as a key step in ecological and economical construction in this area. On the other hand, water was the limiting factor and crucial for ecological and economical construction, and necessary for agricultural production after conversing cropland to forest and pasture. The strategy for pasture establishment based on soil moisture balance was also presented.
