Diversity investigation and sampling method of plant community of wetland

Abstract

The invention relates to a diversity investigation and sampling method of a plant community of the wetland. The method comprises steps as follows: an investigation point is selected according to different wetland types in the following modes; belt transects and quadrats are set; investigation content is determined. According to the diversity investigation and sampling method of the plant communityof the wetland, targeted sample point selection, belt transect setting and quadrat setting methods are designed according to different types of wetland such as rivers, reservoir ponds, lakes, swamp and the like. The diversity data of plants can be obtained with the method, and the relation between the environment factor gradient and plant diversity can also be represented.

Description

technical field [0001] The invention relates to the field of wetland ecology, in particular to a wetland plant community diversity investigation and sampling method. Background technique [0002] Wetlands refer to natural or artificial swamps and other shallow water areas with still or flowing water bodies, including water areas whose water depth does not exceed 6 meters at low tide. Wetlands, forests, and oceans are called the three major ecosystems in the world, and they are widely distributed around the world. A large number of animals and plants live in the wetland ecosystem, and many wetlands are listed as nature reserves. [0003] Wetlands are an important "species gene pool" of the earth's surface ecosystem. As one of the important living environments for humans and many wild animals and plants, wetlands are extremely rich in biodiversity. The investigation and sampling of wetland plant community diversity are extremely important for the study of wetland ecological ...

Problems solved by technology

However, most of these methods are aimed at forest plant communities, and the sample point selection method for the diversity of wetland plant communities is too simple and has poor operability.
