yuan, an increase of 17.5%; local government general budget revenue of 500 million Yuan, ... Painting, model culture creates new Ma Church community, creating Lake scenic spot culture education base, received high evaluation from provincial and municipal discipline Inspection Commission, the people's daily special report. Constantly promote independent Commission against corruption culture construction to rural extends, created established Dahlin rural industry Park independent Commission against corruption culture positions, formed has a support "service low double excellent" of members lead team, constantly perfect and established Park funds assets management, and village audit supervision, and villagers democratic financial, system, strengthening Park party, and Chief, and financial, full public, powerful to guarantees has new rural construction, by city rural style clean government inspection unit led of height evaluation. 　　Through the implementation of honest and clean government cultural construction, and effectively educate the broad masses of party members and cadres and consciously regulated behavior and discipline, honesty in politics and culture to create a good atmosphere and fresh development environment. Although we in implement implementation independent Commission against corruption guidelines aspects made has must effectiveness, but away from superior of requirements also exists must of distance, main performance for: a is system enough sound, education, and supervision, and prevention, and punishment, aspects long-term mechanism also enough perfect, especially in enrollment bid work regulatory aspects also needed strengthening; II is regulatory supervision exists lost of Yu wide, and lost of Yu soft, investigation illegal disciplinary case of efforts also needed strengthening, individual sector and cadres also different degree exists treat gift, not to benefits not do, and mess do of phenomenon; Three for honest work is the new situations and new problems in finding timely enough, treatment measures are not strong enough. 　　To solve these problems, we will proceed from the following five aspects of rectification, make sure to implement the provisions of the code. (A) deepening the learning, enhance the consciousness of honesty in politics. To create event as an opportunity to Excel and learning party, further increasing the governance capability and advanced construction, reinforced rules of the broad masses of party members and cadres awareness, sense of responsibility, sense of honor, improve working ability and level of scientific development. Should make full use of meetings, in particular central group learning opportunity, further strengthening the study and education of the code, the intensive warning education, education the majority of party members and cadres known fear, knew fear, honesty in politics of tension the strings, consciousness and enhancing the implementation of the initiative. 　　Also, pay attention to apply what they have learned, consciously study results into planning work, new ideas,

施工前先采用挖掘机、推土机、辅以人工进行基面及坡面清理，主要把基面及坡面上的建筑垃圾、淤泥质土、树根、荆条根、草皮等杂物清除干净new measures to promote work, the courage to take responsibility, dare to break hard to ensure district, Government decisions and arrangements to implement. (B) strengthening supervision, severely punish acts of violation. One is to open the channels of supervision. Vigorously promote the party affairs public, open, widely accepted supervision by the masses, pay attention to social groups and public opinion supervision, the powerful force formed to urge party members and leading cadres properly exercise their powers. Second, strong supervision and inspection. Democratic life into full play, important briefings, reports related to personal matters and evaluation of cadres ' study of inner-party supervisory system, a comprehensive grasp of guidelines for the implementation of the independent Commission against corruption-related cases of leading cadres of party members, focus on strengthening key areas of project selection, funding, officials monitor, detect and rectify the problem, promote honesty in politics. Third, strengthen disciplinary investigation. Seriously the implementation of JI ...
　Recently, the County leading bodies at the county level to carry out "three trees" practice, which is to improve the governing ability and promoting the development of XX effective measure. I carefully follow your deployment requirements, and actively participate in the "three trees" campaign. Read Group, prepared by the Department in the near future of the ideological and political construction of leading cadres in the city reader, read the relevant information, larger harvest, inspired. I think the ability of repelling is to strengthen the party's governing capacity in questions of the construction of meaning, an important topic remains in front of party members and cadres at all levels, we need to further explore and ponder. The ability of repelling the name suggests, is asking party members and cadres at all levels in particular, leading cadres at all levels, not only ourselves, establish a correct concept of the independent Commission against corruption, political integrity, self-discipline, rejection of corruption, made for the people, pragmatic, honest leadership, and strengthen the sense of responsibility, earnestly implement the responsibility of uncorrupted, implementation of the baolian anti-corruption measures to ensure the realization of business-building, construction of a win-win situation. Next, I combined with their thinking, experience and contact XX practical, on how to enhance the ability of repelling, on four aspects of cognition. 　　Irregularities, please comment. First, the construction of the propulsion system, and enhance the system of corruption since the founding of our party, have been thinking about tackling corruption. Currently, democratic legal system, management system and supervision mechanism is not perfect, administrative acts are not very standardized, Enterprise behavior and market behavior, corruption presents a diverse, pluralistic, complex trends, this shift the struggle between the two, will accompany
