晚清民国,随着摄影在中国的传播,新奇的视觉形式给中国艺术带来巨大的影响,也改变着大众的审美。在绘画领域,这种审美诉求变化首先表现在写真肖像画中。王一亭、吴昌硕作为海派领军人物,是这方面较早的实验者。王一亭以其敏锐的直觉和现代意识,较早关注到摄影,并在文人写真肖像画中将民间的写实技术与文人的写意画风相结合,根据自身的绘画特点和时代审美需求创造了无量寿佛图式的写真肖像画,他1919年创作的《一亭先生五十三岁画像》可以看作这种新时尚的开端,恰恰与摄影在20世纪二三十年代出现第一次繁荣遥相呼应。审美和社会的双重变革在此过程中扮演了重要的角色。这种类型的文人写真肖像画蕴含的现代思考和探索,不仅影响了其他类型的写真肖像画,而且对20世纪后半期的中国人物画创作也产生了重要影响。

建立贫困农户多目标发展评价体系,实现不同发展目标下的相对贫困的精准识别与动态监测,成为新阶段扶贫开发的迫切需求。论文面向精准扶贫、乡村振兴和可持续发展战略,基于贫困农户的短期、中期和长期目标,构建基于G-TOPSIS综合评价方法的贫困农户多目标发展评价模型,结合障碍度模型揭示不同发展目标下贫困农户的发展水平、发展差距及其致贫因素,并基于地理探测器对不同发展水平农户减贫的影响因素进行探测。以云南省福贡县为例的研究区实证结果表明:①研究区目前仍存在大量未脱贫农户,脱贫攻坚的压力依然较大,全面脱贫是福贡县当前最紧迫的发展目标;已脱贫人口距全国和全省农村居民平均发展水平还有较大差距,仍处于相对贫困状态,具有较高的贫困脆弱性,防止返贫、缓解相对贫困的任务艰巨。②短期目标下,主要致贫因素为劳动力受教育年限、卫生厕所、安全住房、家庭人均纯收入、家庭健康状况;中长期目标下,与全国和本省相比,家庭人均纯收入、劳动力受教育年限、安全住房为主要发展短板。③不同发展水平贫困农户空间分布特征存在较大差异,贫困空间分异受基础设施、地形条件、经济区位、自然资源、交通区位等因素的综合影响,农户发展水平越低,空间异质性越强,受地理环境的影响越大。研究结果可为减贫与发展战略的实施与监测提供决策依据与可靠的技术决策支持。

对任伯年写真肖像画的研究多集中于作品的内部问题,而对于作品风格形成的外部环境考察相对较少,对艺术家和赞助人关系的考察无疑为此提供了一个研究视角。胡公寿、吴昌硕、高邕之等文人画家,既是任伯年写真肖像画的定制者,又是合作者。尤其是胡公寿和任伯年的书画唱和,成为任伯年写真肖像画一种特殊的赞助模式,这对于任伯年扩大交游圈以及进行书画宣传具有重要作用。任伯年对不同的定制者采用了类型化的写真肖像画创作方式,既保证了创作的数量,又始终保持较高的艺术水准。这些影响了任伯年写真肖像画风格的形成,也使其在19世纪末海上画坛占有重要地位。
