The relationship between foreign trade and economic management has always been an important research content of development economists and international economists. Regional economy is an important part of the national economy and a spatial system of the national economy. According to its essence, a regional economy is a national economy with regional characteristics. An international foreign trade is based on regional foreign trade. The comparative advantage and realization model of a country’s participation in international division of labor and foreign trade are based on the regional competitiveness of resources in each region of the country. Therefore, the economic development concept of international trade theory can be used not only for analysis of macroeconomic development, but also for guiding economic practices in different regions within a country. Regional participation in foreign trade within a country is not only conducive to giving play to regional comparative advantages, improving labor efficiency, saving social labor, and increasing social wealth; it also helps to attract competitive mechanisms and introduce foreign advanced technology, production methods, economic systems, equipment, and management experience to generate latecomer advantages and realize the reconstruction of regional comparative advantages.
Therefore, this book analyzes and discusses foreign trade and economic management in detail from the content of seven chapters, hoping to have some help.
The main content of mineral resources exploration is prospecting, which refers to the working process of using the ore-forming theory and known ore-forming laws, according to the geological conditions of the working area, using remote sensing technology, geology, geochemistry, geophysics and other methods to find deposits. According to the principle of step-by-step and step-by-step, mineral resources exploration can be divided into four stages: pre investigation, general survey, detailed investigation and exploration. Its tasks are respectively to make a prospective evaluation of regional mineral resources, submit the deep exposure point, submit the exploration point and submit the deposit. The work in each stage of mineral exploration should be guided by the analysis and research of the metallogenic geological conditions in the region, and the comprehensive prospecting method should be adopted according to the geological characteristics of the region and local conditions, so as to achieve the goal more scientifically and economically.
Geotechnical engineering is based on the theories of soil mechanics, rock mechanics, engineering geology and basic engineering. It is a marginal discipline formed by the combination of geology, mechanics, civil engineering, material science and other disciplines. At the same time, it is also a discipline closely combined with geology and engineering. It mainly solves the engineering and technical problems of rock and soil in various projects. As far as its connotation and attribute are concerned, it belongs to the category of civil engineering and plays an important role in civil engineering.
As special engineering materials, rock and soil are different from concrete, steel and other artificial materials. It is the product of nature. It is different with different natural environment, so it shows different engineering characteristics. This leads to the complexity and variability of geotechnical engineering, and the larger the scale of civil engineering, the more prominent and complex the geotechnical engineering problems. In practical projects, geotechnical problems and foundation problems are often the main factors that affect investment and limit construction period. If they did not handled properly, they may bring disastrous consequences. With the continuous expansion of the scale of civil engineering, geotechnical engineering has different branches, and geotechnical investigation is an important branch of geotechnical engineering.
The major of geological engineering includes the traditional engineering geology and prospecting engineering. It is an indispensable major in the national economic construction of our country. With the development of human society and technological progress, its position is becoming more and more important, and its application field is becoming more and more extensive. In addition to serving the traditional geological prospecting, geological engineering is also widely used in industrial and civil buildings, major infrastructure construction, geological disaster prevention, unconventional oil and gas resources development, marine resources investigation and other fields, which is closely related to people's production and life.
With the smooth advancement of the construction of a new socialist countryside and the development of modern animal husbandry, livestock and poultry farming has not only gradually embarked on the road of scale, standardization and industrialization, but also has become one of the important pillar industries that increase farmers’ income. However, some problems still restrict the development of animal husbandry to a certain extent, such as unfavorable increase in the penetration rate of good breeds in livestock and poultry production, poor popularization rate of scientific breeding methods, and the insufficient implementation of disease control systems. Therefore, based on many years of production and teaching practical experience, from the practical, practical and effective point of view, in the sf serving the countryside, farmers andpirit o agriculture, the author has compiled “Technology of Animal Husbandry and Breeding Safety”.
In the preparation of this book, new production technologies in this field have been absorbed and adopted, especially in accordance with the actual production process of livestock and poultry breeding and with reference to relevant national vocational qualification standards, the learning content has been restructured and the learning sequence has been reorganized in order to make learning content and the learning process more close to the actual production, so as to cultivate the ability of learners to scientifically organize livestock production and solve practical problems in production.
The writing of the series fully considers the learner’s knowledge background, learning habits, and cognitive ability. The explanation of theoretical knowledge is concise and easy to explain. The skill training is based on the main task of breeding and production. It is close to production and targeted. It has strong practicality, scientificity and advancedness.
This book emphasizes the people-oriented concept and follows the principle of replacing the standard theory teaching mode with flexible and changeable training forms, which is characterized by the combination of theory and practice. It covers a wide range of contents, allowing learners to master as much useful information as possible with limited energy and time. Based on the present and the future; this book strives to be easy to understand. The author sincerely hopes that this book will become a good teacher and friend for learners to seek a skill, improve their skills, understand the development of the agricultural industry.
This book can provide production guidance for animal husbandry and veterinary technicians of various scale breeding farms, and a large number of breeding professional farmers. It can also be used as a teaching book for vocational education of animal husbandry and veterinary majors, as well as professional training materials for professional farmers and college student village officials.
The compilation of this book has been enthusiastically guided and assisted by the production line technical experts of many production enterprises, and I would like to express my thanks here.
Due to the limited level and ability of the author, the shortcomings are inevitable. Suggestions for improvement will be gratefully received.
The process of water resource development and utilization is nothing more than the process of open source, throttling, pollution reduction, and efficient allocation. In this process, science and technology play a vital role. Urbanization refers to a historical process in which the rural population is constantly shifting to towns, and the secondary and tertiary industries are converging to towns, thereby increasing the number of towns and expanding the size of towns. Its main manifestations are that with the development of social productivity in a country or region, the advancement of science and technology, and the adjustment of the industrial structure, the migration of rural residents to urban areas and the transfer of rural labor employment to urban secondary and tertiary industries. The process of urbanization is also a reflection of the social changes experienced by various countries in the process of industrialization and modernization.
Urbanization is not only an increase in the population and number of cities, but also the further socialization of cities and the intensification of resources. It is a complex process of spatial changes and social and economic development.
