我国天然草原约43亿亩,占国土面积的29%。但由于我国天然草地空间分布的不平衡性及降水季节、年际的不均衡性,导致草地产草量高低相差悬殊,丰、欠年际可相差0.5——1.5倍。我国大多数草原地区(无论准平原性台地及山地)均为冬春严寒地区,枯草期长达7—9个月。而我国人工草地建设速度缓慢,人工草地、半人工草地及饲料
About 43 million mu of natural grassland in China, accounting for 29% of land area. However, due to the unbalanced spatial distribution of natural grassland and the seasonality of precipitation and interannual imbalance in the natural grassland in China, the yield of grassland varies greatly. The difference between abundance and deficit can vary from 0.5 to 1.5 times. Most of China’s grassland areas (regardless of quasi-plains and mountains) are winter and spring harsh areas, hay for up to 7-9 months. The construction of artificial grassland in China is slow, artificial grassland, semi-artificial grass and feed
