In 1866, German Haider proposed "ecology"

American Oldham pointed out that ecology is the science that studies organisms, physical environment and human society.

Research object: Ecology studies the relationship between organisms (including humans) and the environment

Ecology mainly studies from individual organisms to the biosphere, forming corresponding sub-disciplines, such as individual ecology, population ecology, community ecology, ecosystem ecology, landscape ecology and global ecology.

Garden ecology also belongs to the category of applied ecology

Decando introduced accumulated temperature into ecology

Liebig proposed the law of minimum factors of plants

Due to the different natural conditions in various places, the flora and vegetation properties are very different, and the understanding and working methods are also different. Therefore, four schools of thought with different research focuses have emerged.

Tansley proposed the concept of ecosystem

Lindemann proposed a method for grading organisms in ecosystems according to trophic levels.

Central idea: Combining all the advantages of urban life with the beauty and welfare of the countryside is of epoch-making significance in the history of modern urban planning development.

Garden ecology belongs to the category of applied ecology. It is a science that studies the interaction between residents, organisms and the environment within the garden space. It takes garden plants and urban environment as the main research objects, and aims to build a healthy living environment. It is reasonable Utilize resources to regulate the relationship between humans, organisms and the environment to achieve sustainable urban development.

Ecological width: the size of the adaptive range of each species to ecological factors

Ecotype: Different individuals or groups of the same species undergo divergence reactions under different ecological and environmental conditions for a long time, and form genotypic groups with different morphological, physiological and ecological characteristics after genetic differentiation.

Domestication: The process by which plants adjust the tolerance range of one or more ecological factors when living under environmental conditions that deviate from their optimal survival range for a long time.

Tolerance factor: Among many ecological factors, the ecological factors that limit the growth and development of plants or even kill them are limiting factors.
