煤炭资源在我国能源资源中占主导地位,但我国煤炭资源开发秩序混乱,利用粗放,安全事故频发。造成这些问题的原因主要是:资源规划和市场需求难以衔接,政府控制力低与生产集中度低,以及利益追逐和政策导向等方面的问题。对煤炭资源开发秩序的规范及资源整合,应从体制机制方面入手,基础管理层面,重在落实;市场机制层面,加强整合;政府管理体制层面,加快体制建设,提高调控能力。 相似文献

Land management is inevitably linked to the regulation of activities of its proprietor or operator stipulated by legislation and documents of territorial planning. In Lithuania, as in many European countries, territorial planning is a key measure for the formation of landscape and the alteration of its elements. With the help of territorial planning documents, governing authorities has the opportunity to orderly regulate the layout of long-term stable elements of landscape and the sustainable territorial development. However, in comparison with other European Union (hereinafter – EU) countries, territorial planning system valid in Lithuania until January 1, 2014 is still “young” and having specific features with former countries of the Soviet bloc legal regulation. The system did not provided a consistent and sustainable territorial development mechanism: there was the lack of measures allowing to manage the development processes of residential areas and implementation of territorial planning documents (especially the municipal master plans) solutions for the creation of a harmonious functional spatial system. The aim of the present paper is to assess the regulation of legal relations of territorial planning in Lithuania and the EU member states. The assessment summarizes processes of the formation of a landscape during the territorial planning, introduces new opportunities to more accurately predict the results of the current process of landscape planning, and highlights legal and sustainable elements of territorial planning system optimization. As can be seen from the assessment carried out, one of the most important territorial planning objectives was and still remains the balance of mutual relations (hierarchy of plans) of territorial planning documents in shaping the cultural landscape to ensure the rational distribution of the land fund, combining a variety of activities as well as often different land users’ and public interests. Therefore, the implementation of the territorial planning reform of Lithuania capacitates for the transition to an integrated territorial planning, ensuring sustainable development. 相似文献

In 2017, the Chinese government implemented a national strategy of \"Rural Vitalization\" that sought to realize full-scale rural vitalization. However, is it possible to achieve vitalization for all the villages in China? How should their development potential be determined? This paper identified and analyzed the \"element-composite\" messages of rural development based on 99 exemplary sites of “Beautiful Villages” in China. Combined with the projection pursuit classification method, a diagnostic system of rural vitalization was established; then, Dehua County was taken as a case study for an in-depth analysis. Based on national data analysis, the final results indicated that livelihood resources (LR), agglomeration effects (AE), location and transportation (LT), cultural/natural landscapes (CN), and economic circumstance (EC) are essential elements for successful rural development. Additionally, EC was the only exogenous element, while the remaining elements were endogenous. Furthermore, the villages with better EC presented urbanization rates of 38∼82 % and Engel coefficients of 29∼41 % in their counties; exemplary sites lacking LR, CN, LT, and AE account for 13.13 %, 19.19 %, 26.26 %, and 60.61 % respectively, so the indispensability of these elements decreases progressively in sequence. Only 2 % of villages rely on single element for success, therefore, the composite pattern of development element was also critical; 10 out of 16 types were found to successfully facilitate village development, among which, the type of R-a-L-C (32.32 %) and R-A-L-C (15.15 %) were considered as the greatest potential patterns for vitalization. Finally, by means of the diagnostic system, the ratio of representative villages for high-low potential in Dehua County is evenly split; then, development paths, and land use policies that match with paths were proposed, on the basis of development potential and “element-composite” condition of themselves. 相似文献

The paper discusses the major changes necessary for the agricultural higher education system in Central and Eastern Europe, including the former Soviet Union, to meet the challenges created by overall reforms in the food and agricultural sector as well as the adjustment of the global system of agricultural education. The issues arising from the need for reforms in the agricultural education system are presented in an overview of the inherited features of the system, an assessment of the current situation, a status report on the reform attempts and a discussion of the critical issues for the future. 相似文献

以安徽省地勘局为例,地勘事业单位企业化改革虽取得较大成绩,但地勘企业面临的经济基础薄弱、主要职能不适合企业化、改革缺乏顶层设计等困难决定了暂不具备全盘企业化的条件,只能走公益类事业单位改革之路。具体是改为公益一类还是公益二类,各单位只有在明确职能定位、分清主业方向的基础上,对照条件、合理定位、科学分类,选择符合自身发展实际的改革路径才是正确之举。同时,政府相应的扶持政策也是改革成功推进的必要保障。文章针对划分为公益一类、二类的地勘单位提出相应扶持政策建议。 相似文献

Yearly production and reproduction data on dairy farms in The Netherlands were obtained to determine whether management information systems significantly improved herd performance variables (management information systems (MIS) effects). The analysis included 357 adopters of a management information system and 357 herds were used as controls. The data comprised years 1987 through 1996, and included for the adopters both the ‘before’ and ‘after’ period. Panel data analysis enabled to estimate MIS effects both within and between farms, allowing for a separation of farm‐specific effects and common (trend) effects. Adoption and use of a management information system resulted in a significant annual increase in rolling herd average milk (carrier) and protein production of 62 and 2.36 kg per cow, respectively. Calving interval was shortened by 5 days. The pay‐back period was approximately 5 years of the system (including the hardware), and therefore, MIS appears to be economically profitable. 相似文献

The cadastral systems used in each country and region have developed through the centuries to their current form. We cannot assume that the current situation will remain the same from this point to the future. There are signs in recent studies and development projects throughout the world that those cadastral systems which are traditionally seen as well-functioning also need to be renewed as society changes at a rapid pace.This study is set up to analyze the future needs of a cadastral system and registers related to it in Finland. The objective of the study is to reveal future themes affecting the operational environment of the cadastral system by using research methods provided by futurology. The method used in this study is called environmental scanning and it consists of three phases: collecting events, recognizing phenomena and combining the phenomena as themes.The study analyses 352 literature sources and reveals 14 different future themes in the operational environment of the cadastral system, which are economic pressure, demographic changes, development of technology, transparent society, safety, environmental values, globalization, digitalization, know-how, quality, political change, soft values, public-private partnership and crowd sourcing. The future themes, their possible relations between each other and their significance for the cadastral system are analyzed by using the concepts of megatrends, trends, wild cards, driving forces and weak signals and reflecting the results to research made in the field of land management internationally.The results can be used when renewing a cadastral system, in order to consider possible future themes that may affect the system. Detecting and recognizing the future themes provides an opportunity to react and change the course of action in order to adapt to the future. The results are not only usable in the Finnish context, but can also be applied in other countries development of their cadastre and as part of environmental scanning. 相似文献
