摘要：Empowering the value realization of ecological products with a digital economy is an important path for achieving the transformation of“two mountains”and the construction of ecological *** on the panel data of 30 provinces in China from 2011 to 2022,a fixed-effects model was used to empirically test the impact,heterogeneity and mechanism of the effects of the digital economy on the value realization of ecological *** analysis revealed three key findings.(1)The digital economy has a significant driving effect on improving the ability to realize the value of ecological products,and this effect is still applicable in a variety of robustness tests such as shrinking the years,replacing explanatory variables,and endogeneity tests.(2)The rise of the digital economy affects the value realization of ecological products to different degrees in different regions,especially in the eastern region,while the effect in the central region is not obvious.(3)The analysis of mechanistic variables indicated that the digital economy has an impact on the value realization of ecological products through the development of green finance and government ***,the government should design differentiated and multi-level support policies for the realization of ecological product value according to the heterogeneity of natural resources,ecological potential and the levels of digital economy development in different regions,and it should strengthen the control of non-environmental protection behaviors of the *** should accelerate the digital transformation of the entire production,distribution,circulation and consumption chain of ecological products,and actively develop financial products and services that meet the characteristics and needs of ecological products.

摘要：为了提升昌吉回族自治州葡萄酒庄旅游服务质量,选取昌吉州10家代表性葡萄酒庄为研究对象,采用AHP-FCE模型,从基础设施建设、旅游服务接待、旅游服务项目、运营与管理4个层面构建昌吉回族自治州葡萄酒庄旅游服务质量评价体系。评价结果得出,昌吉州葡萄酒庄旅游服务质量整体得分2.02,表明旅游服务质量中等偏差。据此提出加强基础设施建设、提升服务接待水平、注重旅游商品开发和旅游线路设计、完善酒庄管理制度和培训机制等相关建议。

摘要：在我国儿童友好城市建设如火如荼的时代背景下,成人主导与儿童缺位导致建成户外游戏空间忽视了儿童真正的游戏需求,探索儿童对城市户外游戏空间的需求迫在眉睫。该文基于儿童参与式设计实践,通过草图绘制、模型制作、问卷调查等方式对成都市6~14岁城市儿童的户外游戏空间需求进行深度调查。结果发现,相较于传统游戏场,更多元的环境要素、更自然的空间设计、更现代的基础设施及更冒险的游戏形式对儿童游戏行为具有积极影响。基于上述成果,研究对建设满足儿童真实需求的儿童友好型城市户外游戏空间提出相应优化策略,以期为儿童参与式设计实践模式构建及儿童友好型城市空间建设提供参考。

摘要：目的评估生理盐水试验（SIT）在原发性醛固酮增多症（PA）诊断中的价值及最佳诊断切点，同时分析钠盐摄入量对SIT的影响。方法通过前瞻性设计，对纳入的236例PA高危患者均进行筛查试验、SIT和氟氢可的松试验。以氟氢可的松试验作为PA的诊断＂金标准＂，构建SIT诊断PA的受试者工作特征（ROC）曲线。根据24 h尿钠水平，将患者分为低盐、正常盐及高盐组，分析钠盐摄入量对SIT的影响。结果最终236例PA高危患者中有PA 134例，原发性高血压（EH）102例。SIT后血浆醛固酮浓度（PAC）的ROC曲线下面积（AUCROC）为0.974（0.957，0.991），高于SIT后血浆醛固酮/肾素浓度比值（ARR）及试验前后PAC抑制率的AUCROC[0.900（0.862，0.938），0.752（0.690，0.813）]，差异有统计学意义（P〈0.01）。以SIT后PAC 8.0 ng/dl作为PA的诊断切点时，敏感度和特异度分别为88.1%、95.1%。不管在PA还是EH患者中，低盐、正常盐及高盐组之间SIT后的PAC水平差异均无统计学意义（P〉0.05）。结论SIT后PAC为诊断PA的最佳指标，推荐切点为8.0 ng/dl。
