摘要
草原鼠荒地是因鼠类活动和超载过牧等原因引起的严重次生裸地。在采取灭治措施的同时,组装围栏封育、施肥、整地、补播、管理以及招鹰控鼠等生态调控措施,治理后第四年,高原鼠兔持续控制效果达96.1%,高原鼢鼠达98.3%;植被恢复明显,可食牧草高度平均增加14.4%,植被盖度平均增加36.0个百分点,地上生物产量平均提高231.3%;植物群落结构改善,可食牧草比例提高,禾本科牧草平均提高18.2%,莎草科牧草平均提高4.3%,豆科无明显变化,杂类草平均下降17.8%,毒害草平均下降4.8%。
The secondary bare land caused by rodent damage and over grazing is real risk to grasslands. In the meantime of rodent controlling, the support measurements such as fencing, fertilizing, soil preparation, supplemental seeding, management and attracting hawks were taken out and lasting in 4 years. The final results declared that sustainable control effects of Plateau Pika reached 96.1%, Plateau Zokor control effects amounted to 98.3%. The grassland vegetation has been restoring and edible grass height increased 14.4%, the vegetation coverage increased an average of 36.0 percentage points, biological yield increased an average of 231.3%. Plant community structure improved and the proportion of edible grasses changed as thus： Gramineae Cyperaceae increased an average 18.2%, Sedge increased 4.3%, Leguminous were no obvious changes, forbs decreased by an average of 17.8%, poisonous grass decreased by an average of 4.8%.
