摘要:
【目的】以内蒙古陈巴尔虎旗为对象,评价自实施草原生态保护补助奖励政策后,草 畜平衡的效果,为后期继续实施草畜平衡政策提供政策依据,更好地促进草原生态系统良性 循环,实现草原畜牧业持续发展。【方法】利用2010—2018 年陈旗的遥感数据、地面样方调 查数据进行最优估算模型建立,反演地上生物量,并利用牧业统计数据计算草畜平衡状况。 【结果】(1)建立幂函数能较好模拟产草量与其对应NDVI 值的相关关系;(2)反演草原产 草量表明,实施草原生态保护补助奖励机制政策后,草原植被平均产草量持续增加,2018 年草原植被平均产草量1 231.76 kg/hm2,往年同期相比处于最高值;(3)内蒙古陈旗2010— 2018 年的平均草畜平衡指数8.11%,草畜平衡指数在逐年增大,从2010 年的欠载6% 增加 大超载6.17%,2018 年接近临界超载。【结论】建议内蒙古陈旗要严格控制牲畜数量,调整 牲畜结构,增加牲畜良种率,加强草畜平衡监督管理,使草原生态环境总体逐渐转好,达到 草畜良性循环。

Abstract:
[Purpose]Taking Chenbalhu Banner of Inner Mongolia as a study region,the effect of grassland-livestock balance since the implementation of grassland ecological protection subsidy and incentive policy was evaluated for the further implementation of grassland-livestock balance policy,so as to promote the virtuous cycle of grassland ecosystem and realize sustainable development of grassland animal husbandry.[ Method]Based on the remote sensing data and ground sample survey data of Chenbalhu Banner from 2016 to 2018,the optimal estimation model was established to retrieve the aboveground biomass and to calculate the balance of grass and livestock by means of the animal husbandry statistics.[ Result]1. Establishing power function could fairly simulate the relationship between the yield of grass and its corresponding NDVI value. 2. Inversion of grassland yield showed that the average grassland vegetation yield continued to increase after the implementation of the incentive mechanism for grassland ecological protection. The average grassland vegetation yield in 2018 was 1 231.76kg/hm2,which was the highest in the same period in previous years. 3. Referring to“ Technical Method of Monitoring and Early Warning of Resources and Environment Carrying Capacity”( 2016),the livestock overload rate was applied to evaluate the balance of grass and livestock. In 2010 and 2015,the overload rate was 6.0%,1.2%,and in 2017 and 2018,the overload rate was 9.14% and 6.17%,respectively, which basically reached the balance of grass and livestock while approaching the critical overload. [Conclusion]The ecological grassland environment in Chenbalhu Banner has been gradually improved in a few areas,but is still worsening in general. Therefore,in order to implement the balance between grassland and livestock,the number of livestock have to be controlled to adjust the structure of livestock,increase the rate of improved breeds of livestock,thus achieving a virtuous cycle of grassland and livestock.
