Land resource refers to the land that can be used for agriculture, forestry, animal husbandry or other purposes. It is the basic material and labor object of human existence, with two contents of quality and quantity. In the process of utilization, it may be necessary to take different types and different degrees of transformation measures. Land resources have certain spatiotemporal characteristics, that is, under the technical and economic conditions of different regions and different historical periods, the contents may be inconsistent. For example, large area marsh is difficult to control because of water logging. In the historical period of small-scale agricultural economy, it is not suitable for agricultural use and cannot be regarded as agricultural land resources. But today, it is the agricultural land resources that have the technical conditions for management and development. Therefore, some scholars think that land resources include two aspects: the natural attribute and the economic attribute.
This book mainly carries on the comprehensive management and the analysis from six chapters to our country land resources management and the real property economy. It proposes the solution to the present existing questions. We hope that it can have certain help.
In the development of national economy, water conservancy is an important part. After a long time of development and evolution, remarkable results have been achieved. However, from the current actual situation, there are still some deficiencies in the management of water conservancy projects in China. It does not only affects the economic benefits of the project construction, but also the social economic development and people's daily life and production. Therefore, in the future development, we must enhance the importance of water conservancy project management, so as to better adapt to the requirements of the development of the new era.
In addition, because water conservancy projects are often built in some areas with underdeveloped traffic conditions, the transportation cost of mechanical equipment and materials will be relatively high. In the process of practice, if a perfect and feasible construction plan cannot be formulated, the quality of project construction cannot be controlled and guaranteed. Through the development of project management, the above problems can be effectively solved to achieve the whole process management. This can not only save a lot of cost and time for enterprises, but also guarantee the quality of engineering construction. In the process of practice, the enterprise needs to send out professional project management person and set up a special project management department to comprehensively optimize the construction scheme, so as to complete the project construction task with quality and quantity and highlight the social value of water conservancy project to the maximum extent on the premise of cost saving.
This book is divided into 11 chapters to analyze the contemporary water conservancy project construction and project management in detail, and put forward solutions to the problems found. We hope it can help relevant staff in work.
在国民经济发展中， 水利事业是至关重要的组成部分， 经过长时间的发展演变，现已取得显著成效，但从目前实际情况来看，我国在水利工程管理工作中仍存在一些不足，如此不仅对该工程建设经济效益产生影响，同时还给社会经济发展以及人们的日常生活生产带来一系列安全隐患。为此，在今后发展中，一定要提升对水利工程管理工作的重视程度，从而更好地适应新时期发展的要求。
此外，由于水利工程经常会建设在一些交通状况不发达的地区，机械设备材料的运输费用也会相对较高，实践过程中，若不能制定出完善可行的施工方案，便无法对工程建设质量进行控制和保障，而通过工程管理工作的开展，则可有效解决上述问题，实现水利工程的全过程管理，不仅可为企业节约大量成本和时间，同时还可为工程建设质量提供保障。实践过程中，企业需派遣出专业的项目管理人员，并成立专门的项目管理部门， 对施工方案进行全面优化， 从而可在节约成本的前提下，保质保量地完成工程建设任务，最大限度地凸显水利工程的社会价值。
With the in-depth research and close combination of basic medicine and clinical medicine, laboratory medicine is changing rapidly. As an “ancient” and “emerging” marginal discipline, it plays an important role in the process of disease diagnosis and treatment. With the rapid development of national economy and the continuous improvement of living standards, people’s awareness of health and the transformation of medical model have changed the social demand for medical services, and also put forward new requirements for the positioning of medical laboratory work.
This book is based on the basic theory of blood test, clinical test and biochemical test. Based on the laboratory test and examination diagnosis of various common diseases, it expounds the basic methods and technologies in the physiology and pathology of hematopoietic system, the basis of blood test, the blood disease test, the body fluid test, the male reproductive system disease test, the female reproductive system disease test, the perinatal health care and test, the examination of birth and child diseases, the examination of chromosomal and genetic diseases, the disorder and examination of glucose metabolism, the disorder and examination of lipid metabolism and the disorder of water salt metabolism and acid-base balance and so on. The purpose of the book is: “taking the test as the main line, the clinical as the goal, and the disease as the center”. It has the characteristics of “comprehensive, innovative, practical and pragmatic”. It strives to integrate theory with practice, adheres to the combination of experimental technology and clinical diagnosis and treatment, and combines the development of international new technology with the specific domestic reality, so as to make the majority of medical laboratory workers, clinicians and experimental medical researchers members, teachers and students of medical colleges and universities learn and refer to professional theories, technical knowledge and clinical materials from different levels and perspectives.
Today’s world presents the development pattern of political multipolarization and economic globalization. With the rapid development of science and technology, the competition between countries, regions and regions is more intense. The importance of plundering resources and market has been replaced by the competition of talents, knowledge, information, high-tech development; that is to say, the competition of human resource stock and improvement. As the world’s largest population country, China’s rich human resources have made outstanding contributions to social development. However, this advantage has become an obstacle from time to time on the road of economic construction, and many problems have arisen. For example, the efficiency of market allocation is low, the brain drain is serious, and the contradiction between talent shortage and talent waste coexists. Faced with the problems of talent competition and human resources that have a greater and more profound impact on economic development than product competition and capital competition, how to attract talents, develop human resources, and build a country with a large population into a country with strong human resources has always been the concern of China’s government at all levels, experts and scholars, and the whole society.
This book introduces the elements of human resources management and the relationship between human resources and economic growth. Suggestions for improvement that readers given will be gratefully received.
当今世界呈现出政治多极化和经济全球化的发展格局，科学技术迅猛发展，国家与国家、地区与地区之间的竞争更加激烈，掠夺资源、市场的重要性，已让位于人才竞争、知识竞争、信息竞争、高新技术的开发和发展的竞争，即让位于人力资源存量和提高的竞争。作为世界第一人口大国的中国，其丰富的人力资源为社会发展做出了卓越的贡献。 但是， 这种优势在经济建设的道路上时不时地成为一种阻碍，许多问题应运而生。例如，市场配置效率低下，人才外流现象严重，人才短缺与人才浪费并存的矛盾等。面对比产品竞争、资本竞争对经济发展有更大、更深远影响的人才竞争和人力资源自身所带来的问题，如何招揽人才、开发人力资源，把人口大国建成人力资源强国，一直是我国各级政府、专家学者及全社会关注的问题。
The construction industry occupies a very important position in the development of our national economy. The development of the national economy will inevitably lead to the expansion of the construction scale and the improvement of the technical level. Among them, the renewal and development of the construction equipment construction technology is particularly significant.
