The transformation of dilapidated houses in rural areas is not only a livelihood project related to the broad masses of rural people,but also a major project to win the battle against poverty. Luquan Yi and Miao Autonomous County,Yunnan Province,located in the high mountain and gorge area along Jinsha River,is one of the key counties of poverty alleviation and development with a wide range of poverty and a deep degree of poverty. The incidence of poverty is 22. 21%. Housing security is the focus,difficulty and emphasis of poverty alleviation in this county,the number of dilapidated houses is large,the type is complex,the transformation is difficult,and the implementation cost is *** the beginning of 2017,Luquan County has faced difficulties,explored in depth,pioneered and innovated,and completed the renovation of 54 801 dilapidated houses in an all-round way. It created a road full of characteristics and effectiveness of rural dilapidated housing transformation,and explored a set of effective scientific identification and accurate transformation models for rural dilapidated housing worthy of reference and promotion. Successful renovation of dilapidated houses,combined with industrial poverty alleviation,education poverty alleviation,health poverty alleviation and other accurate poverty alleviation measures,have made Luquan County win a decisive victory in the fight against poverty. By the end of December 2018,the incidence of poverty in the county had dropped to 0. 54%,and 115 poor villages( including 83 extremely poor villages) had successfully shaken off poverty. This paper analyzes and summarizes the concrete methods,main effects,characteristics and bright spots,successful experience,and reference significance of the scientific identification and precise transformation mode of rural dilapidated houses in this county,so as to provide a necessary reference for the transformation of rural dilapidated houses in Yunnan Province and even poor counties in similar

In the industrial targeted poverty alleviation,land circulation is a key process. Based on the national strategy of targeted poverty alleviation,this paper combined the industrial development of targeted poverty alleviation with land circulation. According to the field survey on the current situation of land circulation and promotion of the industrial poverty alleviation in the typical project area of Zhongping Village in Zhongping Town and Jiaowuying Village in Jiulong Town in Luquan Yi and Miao Autonomous County in Yunnan Province,located in the high mountain canyon area of Jinsha River in the upper reaches of the yangtze River in the west of China. This paper summarized and analyzed the organization and operation mechanism,basic practices and main results of the land circulation and promotion of industrial poverty alleviation model in the typical project area of the county. It also summarized the innovation and successful experience of the model,and then came up with measures to further promote the implementation of the model,so as to provide necessary reference for the implementation of land circulation and industrial targeted poverty alleviation for the poverty-stricken counties in Yunnan Province and similar provinces( cities,regions).

Due to the severe restrictions of natural conditions and ecological environment,high-altitude mountainous areas usually become the " hard bones" in the battle against poverty. Xueshan Township,Luquan Yi and Miao Autonomous County of Yunnan Province,located in the alpine valley of Jinsha River,is a major township with wide and deep poverty,and the incidence of poverty is up to 45. 00%. In recent years,Xueshan Township has insisted on the battle against poverty,made effort to develop the Codonopsis pilosula industry,and successfully developed a road to poverty alleviation through C. pilosula industry,and formed a unique industrial poverty alleviation model by the end of 2018,the incidence of poverty dropped to 0. 74%. Based on field survey and interview,this paper analyzes and summarizes the specific practices,main results,practical experience and promotion and application measures of the poverty alleviation model of C. pilosula planting industry in Xueshan Township,in the hope of providing certain reference for the targeted poverty alleviation in similar areas in Yunnan Province and other provinces of China.

为了探究银坑铅锌银多金属矿田的构造特征和找矿潜力,选取区内基底复式褶皱作为研究区,开展野外调查和室内分析。揭示基底褶皱几何学和应力场特征并探讨对成矿的控制作用,重点研究褶皱作用晚期纵张断裂中的SN向交代充填石英矿脉的成矿特征。通过实测褶皱轴迹与两翼产状,分析其几何形态特征为:枢纽走向由北至南为NE→NNE→SN→NNW,翼间角范围为33°~52°,褶皱类型为紧闭陡立尖棱状褶皱。通过褶皱分析法与节理统计法,求得基底褶皱自加里东期至燕山期主应力方向变化为EW→NWW→NNW→NEE。基底地层早期受EW向挤压而形成SN向构造带与大量的SN向褶劈理带。应力场转换期间地层受到的应力由挤压向拉张转换,促进褶劈理带内形成SN向纵张裂隙,为后期NE向矿化提供空间。通过实测与观察,基底褶皱首次发现近SN向矿化石英矿脉充填于褶皱作用晚期的切层纵张和次级横张裂隙。含矿性分析显示,脉中铅、锌平均含量为0.133%和0.190%,金、银的平均含量0.127 g/t和15.33 g/t,具有较高的矿化特征。在桥子坑矿区地表和牛形坝矿区60、104和140中段新发现12条SN向矿脉,表明该区有巨大的成矿潜力。

为分析武汉市土地利用变化及对生态系统服务价值(ESV)的影响,利用1990—2015年遥感影像数据,通过土地利用动态度、土地利用转移矩阵、生态系统服务价值和生态贡献率等方法,揭示了武汉市土地利用变化规律及对ESV的影响。结果表明:(1)武汉市土地利用结构变化显著,耕地、林地和未利用地减少,建设用地和水域增加。土地利用的转移主要发生在耕地向建设用地的转移。(2)研究期内武汉市土地利用综合动态度远超同时期全国水平,建设用地的动态度远高于其他用地类型,城市化建设处于增速。(3)武汉市ESV总量增加,水域和草地的ESV增加,耕地、林地和未利用地的ESV减少。研究期内各项ESV,以水文调节和水资源供给为主,单项ESV变化最大的是水文调节。(4)水域、耕地和林地对ESV变化的生态贡献率较大,三者生态贡献率之和在98%以上,是生态服务的主要贡献者,也是ESV变化的敏感因子。

云南是中国贫困县最多的山区省份,同时也是中国城乡收入差距长期居高不下的典型省份。针对当前研究中未能深入探讨城乡收入差距与各地贫困程度关联性、未能深入探讨各影响因素空间相关性、忽视关键地理因素对城乡收入差距影响等问题和不足,本文将各县按照贫困程度的差异划分为4个类别,使用云南省129个县(市)2010—2018年产业、社会、经济、人口等维度的面板数据,并引入“地形-气候综合优劣度”作为非经济指标,在分析城乡收入差距时空演化和空间格局特征基础上,运用空间动态面板模型深入探析了其影响因素。基于研究结果,认为有必要将缩小城乡收入差距与国家精准扶贫战略、城乡融合发展战略和乡村振兴战略有效衔接。
