What is developmental ecology and what is ecology

In my personal opinion, ecology is second only to philosophy, but above other disciplines of a discipline, it has comprehensive, interdisciplinary and many other characteristics, its research can not be separated from other disciplines, nor will it replace other disciplines, but it has a certain guiding significance for the development of other disciplines. There are many definitions of ecology, the earliest and the most classic, which have been introduced by the friends upstairs. It is the study of the interrelationship between living organisms and their surroundings, including the living and non-living environments.

That is, it does not study the environment, nor does it study living things, it studies the content, so that the two are interrelated. This is the point. As for its development history, in fact, since the beginning of human beings, we have begun to use some ecological knowledge, such as what kind of place to go and what kind of food can be picked.

The earliest ecological ideas in the West, discovered by Aristotle's student Theophrasta during his expedition with Alexander, are related to the local climate and soil. The earliest monograph on the germination of ecology in China is the Compendium of Materia Medica. It is not only a book of medicine, but also explains where and what kind of herbs can be found, which is the germ of the first plant ecology.

There's a lot more to say, and if you have any questions, feel free to communicate.

At present, there is no unified and clear definition of the development stages of ecology, which can be divided into the following stages from the perspective of the development of land ecology abroad; 1. In the embryonic stage of land ecology, the German chemist Liebig pointed out the idea of the circulation of nutrients in plant soil and environment in the 19th century, which can be regarded as the beginning of land ecology. 2. The early ecology marked by the type of land type research, and by the eighties of the 20th century, the landscape was divided into different levels of size, and there was a deep study of different types. The emergence of the concept of land ecosystem has promoted the study of natural factors in land use conditions.

3. The land ecology stage marked by the research of land ecological assessment includes the period of land natural potential evaluation in the 60s and 70s, the land suitability evaluation period in the 70s and 80s, and the comprehensive development period of land ecological assessment in the 90s. There are 8 categories of research contents, namely land system structure and change, ecological function and process, ecological classification and investigation, ecological assessment, ecological planning and design, ecological restoration and reconstruction, ecological management and protection, and ecological economy.

Basic concepts of ecology.

Ecology is the science that studies the interrelationship between organisms and the environment and the mechanism of their action.

The survival, activity, and reproduction of living organisms require a certain amount of space, matter, and energy. In the process of long-term evolution, organisms gradually develop special needs for certain physical conditions and chemical components of the surrounding environment, such as air, light, moisture, heat and inorganic salts. The material and energy required by various organisms and the physical and chemical conditions to which they adapt are different, and this characteristic is called the ecological characteristics of the species.

Ecological connotations.

The definition of ecology contains three meanings: first, ecology is the science that studies the structure, function and changes of macroscopic living systems in nature, and human beings understand, protect and use nature based on the results of ecological research; Second, the core content of ecology is to study the macroscopic living system and its relationship with the environmental system, which interacts, interdependence, and mutual cause and effect, so that the living system can reach a relatively stable state. The third is that man is a living being, an integral part of the natural world, and has subjective initiative to change nature. From this definition and connotation, ecology is actually a view of nature that human beings understand and transform the world.

In other words, ecology is not only the epistemology of nature, but also the practical theory of protecting and transforming nature, and the unity of human epistemology and practical troublesome theory of nature.

Ecology (ecology) is the study of the relationship between organisms and the environment, between organisms and the biological branches of organisms.

Ecology mainly studies the relationship between organisms and their surrounding environment (including abiotic environment and biological environment), mainly carries out ecological planning, research, construction, transformation and management of industrial ecology, urban ecology and general ecology, etc., so as to build a green ecological environment and reduce urban pollution.

Students mainly learn the basic theories and basic knowledge of ecology, receive scientific thinking and scientific experiment training in basic research and applied basic research, have good scientific literacy, master modern ecological theory and computer simulation and other experimental skills, and initially have teaching, research, development and management capabilities.

Organisms, activities, reproduction require a certain amount of space, matter, and energy. Long-term evolution in living organisms, gradually forming certain physical conditions and chemical compositions of the surrounding environment, such as air, light, moisture, heat, special needs of salts and inorganic salts. The adaptation of various biological substances, energies and their physical and chemical conditions is different, and this function is known as the ecological properties of the species.

None of the living things is isolated: the competition between the same self and mutual aid, the complex relationship between plants, animals and microorganisms. Human beings, in order to meet their own needs, constantly transform the environment, which in turn affects the human living environment.

Ecology is a concept defined by the German biologist Ernst Haeckel in 1866: ecology is the study of the interrelationship between organisms and their surroundings (including abiotic and living environments). It has now developed into "the science that studies the interrelationships between living organisms and their environment".

A relatively complete and independent discipline with its own research objects, tasks and methods. Their research methods are described in three processes: experimental, and quantitative. The introduction of the concepts and methods of systems theory, cybernetics, and information theory has promoted the development of ecological theory.

According to the type of organism studied.

There are microbial ecology, plant ecology, animal ecology, human ecology, etc.

Hierarchy of structure of biological systems.

There are: individual ecology, population ecology, community ecology, ecosystem ecology, etc.

The categories of environments inhabited by organisms are divided.

There are terrestrial ecology and water ecology; The former can be divided into forest ecology, grassland ecology, desert ecology, soil ecology, etc., and the latter can be divided into marine ecology, lake and marsh ecology, watershed ecology, etc. There are also more detailed divisions, such as: plant rhizosphere ecology, intestinal ecology, etc.

The combination of ecology and non-life sciences includes mathematical ecology, chemical ecology, physical ecology, geographic ecology, economic ecology, ecological economics, forest ecological accounting, etc.; Combined with other branches of life sciences, there are physiological ecology, behavioral ecology, genetic ecology, evolutionary ecology, paleoecology, etc.

Applied sub-disciplines include: agroecology, medical ecology, industrial resource ecology, environmental protection ecology, environmental ecology, ecological conservation, ecological informatics, urban ecology, ecosystem services, landscape ecology, etc.
