Coal mining has caused notable disturbance and destruction to the ecosystem，leading to intensified regional carbon emissions. Ecological restoration of abandoned coal mines can improve the physical and chemical properties of damaged soil and increase soil carbon storage. Therefore，ecological restoration of coal mine areas is crucial for improving regional carbon sink levels and environments. Currently，most studies on ecological restoration in Chinese coal mining areas are scattered across the major coal-producing provinces in the Yellow River Basin. Its effect on soil carbon sequestration at a basin scale must be crucially elucidated. In this study，we focused on changes in soil physicochemical properties and enzyme activities after vegetation restoration using an integrated analysis method，combined with climate and soil characteristics in the Yellow River Basin’s coal mining areas to reveal the major factors affecting soil carbon restoration. Our results showed that：① Soil physicochemical properties and enzyme activities were improved significantly after ecological restoration;however，some differences were present among different soil layers. ② Soil organic carbon（SOC），total nitrogen，and alkali-hydrolyzed nitrogen increased by 62.2%，40.5%，and 36.0%，respectively，showing an overall increasing trend with increasing restoration years. From the perspective of vegetation type，mixed forest had the largest increment in SOC. ③ The increase in nitrogen and phosphorus content improved soil fertility and helped to increase soil carbon input from vegetation litter，thus promoting the restoration of the soil organic carbon pool. In addition，average annual temperature and precipitation along with soil type also played important roles affecting soil C restoration. In the future，based on climate and soil characteristics of specific mining areas，suitable vegetation types should be selected from a perspective of C sequestration to enhance C sink of the whole basin. © 2025 Science Press

自然口语对话中,由“还是”构成的选择问句有多种形式,由“还是”系连的并列项不仅在结构上会呈现出不对称性,其功能也呈现出多样性。虽然“或者”与“还是”在书面语中的差异或许体现为“标准析取并列”与“疑问析取并列”的对立,但是在自然口语对话中,用于追加信息时,这种对立有可能被中和;而出现于回应话轮之首的“或者”,用于提出建议,即便采用疑问句法,也不能被“还是”替换。当“还是”位于话轮末形成不完整话轮或单独用作一个话轮时,原有的句法功能弱化、语义被漂白,仅体现言者的互动意图。它作为特定互动行为的载体,具有位置敏感性。“疑问析取并列”不能完全概括“还是”的用法,但能为理解“还是”的功能扩展路径提供可能的解释。

对可再生能源优先发展有不歧视、上网优先以及成本因果三种解释。中国各能源单行法等虽然都有可再生能源优先利用的要求,但并未将其明确为一项原则。在碳达峰碳中和目标下,将可再生能源优先发展作为一项法律原则具有必要性。可再生能源优先发展在法律上存在多重效力困境,表现为立法不协调、执法规范不落地以及司法裁判不统一,究其原因在于可再生能源优先发展内外结构的断裂。正在修订的《可再生能源法》应当明确规定可再生能源优先发展原则,并以此改革和完善可再生能源规划、上网、消纳等法律制度。那种认为可再生能源优先发展有损平等竞争的看法,是对公平竞争和可再生能源优先发展原则的双重误读。
