Impact of grassland contract policy on soil organic carbon losses from alpine grassland on the Qinghai–Tibetan Plateau

Carbon storage in the soils on the Qinghai–Tibetan Plateau plays a very important role in the global carbon budget. In the 1990s, a policy of contracting collective grasslands to smaller units was implemented, resulting in a change from the traditional collective grassland management to two new management patterns: a multi‐household management pattern (MMP: grassland shared by several households without enclosures) and a single‐household management pattern (SMP: grassland enclosed and used by only one household). In 2016, 50 MMP and 54 SMP winter pastures on the Qinghai–Tibetan Plateau were sampled to assess the differences in soil organic carbon (SOC) between the two management patterns. Results showed that average SOC was significantly greater under MMP than under SMP, with an estimated 0.41 Mg C/ha/yr lost due to SMP following the new grassland contract. Based on the government's grassland policy, four grassland utilization scenarios were developed for both summer and winter pastures. We found that if the grassland were managed under SMP, likely C losses ranged between 0.31 × 10⁷ and 6.15 × 10⁷ Mg C/yr across the Qinghai–Tibetan Plateau relative to MMP, which more closely resembles pre‐1990s grassland management. Previous estimates of C losses have only considered land use change (with cover change) and ignored the impacts driven by land management pattern changes (without cover change). The new data suggest that C losses from the Qinghai–Tibetan Plateau are greater than previously estimated, and therefore that the grassland contract policy should be reviewed and SMP households should be encouraged to reunite into the MMP. These findings have potential implications for land management strategies not only on the Qinghai–Tibetan Plateau but also other grazing regions globally where such practices may exist.

有效体育教学模式的创建与实施*

有效体育教学的内涵主要包括三个方面，即，体育教学要重效果，体育教学要好效益，体育教学要高效率。有效体育教学模式是指在“健康第一”思想指导下相对稳定的一种教学程序，其创建步骤主要包括确立教学指导思想、明晰目标内涵、分析教学情境、编选教学内容、创设运作程式。有效体育教学模式的实施要全程渗透健康引领的价值观念，细化体育教学有效性的指标体系，加强教师的有效指导，激活学生的主体参与。     

西方国家碳税收入使用政策比较及其启示

碳税收入使用政策是西方国家碳税制度设计的一项重要内容，其主要基于税收中性原则，将税收收入或投资于环保节能项目，或以税式支出方式降低纳税人负担，确保碳税收入的循环，实现节能减排的目标。在我国碳税制度设计的构想中，应借鉴西方国家税制经验，结合本国现实情况，科学合理地设计碳税收入使用政策，确保碳税调节功能的充分发挥，将碳税发展成培育战略性新兴产业的重要政策工具之一。
