In order to realize rural revitalization in an all-round way and promote the sustainable and healthy development of the economy and society,China is committed to deepening the pace of building a new countryside with Chinese characteristics.The reform of the"Separation of Three Rights"of rural homesteads is a key measure,which aims to activate rural resources,enhance the vitality of rural economic development,and then promote the overall process of rural revitalization.This study selects Juancheng County,Heze City,Shandong Province as a typical case.Through an in-depth analysis of the relevant policy orientation of the national homestead reform and the specific practice of local promotion work,it systematically sorts out the registration of homestead rights,transfer of use rights and relevant policy measures adopted in paid use,qualification conversion,policy publicity and system establishment.After in-depth research on the system reform practice of the"Separation of Three Rights"of homesteads in Juancheng County,this paper reveals the main problems existing in the current reform,including the lack of clear policy support for the mechanism of paid use of homesteads,difficulties in the process of identifying qualification rights and challenges,the imperfection of the transfer mechanism of use rights,and the lack or lag of relevant policies.A series of problem-oriented policy suggestions are put forward,including establishing and improving the system of paid use of rural homesteads,improving the income distribution mechanism,promoting the innovation of the mortgage guarantee system for the right to use homesteads,and optimizing the homestead qualification certification procedures.These suggestions aim to provide a useful reference for the Juancheng County Government in promoting the reform of"Separation of Three Rights"of homesteads,and then promote the rational allocation and efficient utilization of rural homestead resources.

Theoretical Research on Cultivated Land Ecological Compensation Based on Targeted Poverty Alleviation and Development

The effectiveness of targeted poverty alleviation is related to whether China can build a well-off society on schedule. Poverty alleviation is an arduous and urgent major issue in China,and the Party and the government have always been very concerned about and attached importance to poverty alleviation. At present,China’s poverty alleviation and development faces enormous pressures and challenges. Some poor areas actually shoulder the heavy responsibility of ecological protection in the process of national development. The contradiction between economic development and ecological protection is intensifying. Objectively,these poor areas have made outstanding contributions and great sacrifices for the country’s ecological construction. Therefore,it is necessary to balance the two goals of poverty reduction and building an ecological environment and explore a win-win path that is in line with the actual ecological protection and poverty alleviation and development in poverty-stricken areas. Ecological compensation for poverty alleviation is one of the basic contents of the " five-batch" project of China to implement poverty alleviation. Cultivated land is a very important ecosystem on land. On the basis of studying the ecological effects of cultivated land,the implementation of cultivated land ecological compensation has become an important part of the research on ecological poverty alleviation. On the one hand,ecological compensation for cultivated land can support or promote poverty alleviation and development. On the other hand,poverty alleviation and development policies also provide practical opportunities for cultivated land ecological compensation. Carrying out research on cultivated land ecological compensation and practicing this new direction and new poverty alleviation mode is of great significance to promote and improve the construction of ecological system for cultivated land,targeted poverty alleviation and development,and ecological protection of cultivated land. On the basis of combing the national ecological poverty alleviation strategy related policies and sorting out cultivated land ecological compensation theory research,this paper discusses the new mode of cultivated land ecological compensation to assist poverty alleviation and development,reveals the main problems in the current research and practice of cultivated land ecological compensation,and puts forward some suggestions for improving the ecological compensation for cultivated land to promote poverty alleviation and development.

Constitutive Activation OsbZIP62 Improves Plant Height and Yield through Regulating the Expression of Agronomic Traits Related Genes in Rice

Plant height is an important morphological trait that affects crop yield.Several genes related to plant height and yield have been reported in rice(Oryza sativa L.),however,the molecular mechanism underlying the regulation of these traits is still not completely understood.VP64 is widely used as a transcriptional activator to investigate the biological function of genes encoding transcription factors.Here,we identified a novel bZIP transcription factor OsbZIP62 that is involved in modulating agronomic traits in rice.Overexpression of OsbZIP62-VP64(OsbZIP62V)significantly increases the plant height and yield per plant in rice.RNA-seq analysis showed that some plant height and panicle development related genes(i.e.,OsEATB,OsDSS1 and OsGA3ox2)were up-regulated in OsbZIP62V overexpressing rice plants.Besides,OsbZIP62 could also bind to the promoters of several putative target genes.These results suggested that OsbZIP62 plays a role as transcriptional regulator in regulating the expression of genes associated with agronomic traits,and OsbZIP62 fused with VP64 would be useful in crop genetic modification with improved plant architecture and yield.

Work Effectiveness,Problems and Countermeasures of Third-Party Assessment Teams from Colleges and Universities for Targeted Poverty Alleviation

Conducting a third-party assessment on targeted poverty alleviation can effectively avoid the disadvantage that local government plays as both athlete(i.e.performer of poverty alleviation work)and referee(i.e.referee for poverty alleviation effect)in poverty alleviation to ensure the truth of poverty alleviation,and therefore,it is an important part of the work to win the battle against poverty.Since 2016,the thirdparty assessment teams from colleges and universities for targeted poverty alleviation have achieved good results and performance in the assessment on both the effectiveness of targeted poverty alleviation work and the exit of poor counties in China,and they have made due contributions to the cause of poverty alleviation.However,as a new thing,third-party assessment obviously has some problems,mainly including the following:subjective understanding on the long-term nature of rural poverty alleviation is insufficient,and there is a lack of long-term considerations and related mechanism for third-party assessment;affected by policies and institutions,most of the existing third-party assessment teams from colleges and universities have not regarded third-party assessment of targeted poverty alleviation as a cause,and they lack the motivation to actively study the assessment business;and the third-party assessment staff from colleges and universities for targeted poverty alleviation have low stability and high mobility,not conducive to the long-term construction of assessment teams.In order to establish long-term poverty alleviation and prevention mechanisms,these issues must be addressed squarely and relevant countermeasures need to be taken actively to effectively build a long-term mechanism for building third-party assessment teams from colleges and universities for targeted poverty alleviation.

Significance,Path and Typical Cases of Integration of Grassroots Party Construction and Targeted Poverty Alleviation Team Construction in Colleges and Universities

The integration of party construction and poverty alleviation and development is an important form of achieving poverty alleviation in China. Based on the actual case of the integration of the party branch construction of the Institute of Targeted Poverty Alleviation and Development of Yunnan University of Finance and Economics and the construction of a third-party evaluation team for targeted poverty alleviation,this paper elaborated the practical significance and integration path design of the grassroots party construction and targeted poverty alleviation thirdparty evaluation team construction in colleges and universities. Besides,it analyzed the typical case of the party branch in the process of building the party branch of the ' double leader' teachers in the national colleges and universities,and vigorously implementing the development of the party branch construction and the third-party evaluation team for targeted poverty alleviation,and promoting double integration and double promotion. Finally,it came up with recommendations for further strengthening the development of the party branch construction and the thirdparty evaluation team for targeted poverty alleviation( including strengthening the party construction responsibility,promoting the solid foundation,promoting deep integration,strengthening mutual promotion,gathering poverty alleviation talents,and strengthen intellectual support),so as to form a new model of poverty alleviation through party construction and practicing the lofty purpose of serving the poor household wholeheartedly,and provide a useful reference for the grassroots party construction in China to promote poverty alleviation.
