Method for determining number, position and area of tiny-population wild plant protection reserves

Abstract

The invention discloses a method for determining number, position and area of tiny-population wild plant protection reserves. The method includes following three steps: S1, recording number and size of a natural population according to population investigation results, and determining target species population number, total plant number and plant number of each population; S2, determining number and plant number of populations distributed in a built protection area; S3, determining the number, the position and the area of the tiny-population wild plant protection reserves. By the method, the problems that natural protection areas are low in pertinence to specific target species and technical methods for determining the number, the position and the area of the protection reserves lack are solved, definite number, position and area information data are provided for planning and building of the tiny-population wild plant protection reserves, and impact of subjective factors from participating parties like local governments and planning and designing units can be avoided.

Description

technical field [0001] The invention relates to the technical field of wild plant protection, in particular to a method for determining the number, location and area of ​​small population wild plant protection plots. Background technique [0002] Wild plants with very small populations are narrow or discontinuous distributions in the wild, long-term restricted by their own reasons or disturbed by external factors, the population continues to degenerate or decrease, and the population size is lower than the minimum viable population and endangered plants. The protection of very small populations of plants is related to the survival or extinction of plant species, and is an important part of the protection of wild plant resources. At present, my country is implementing the "National Extremely Small Population Wild Plant Rescue and Protection Project" including 120 species of plants, all of which urgently need to be rescued and protected. In the next step, the list of extremely...

Problems solved by technology

At present, in China, the word "nature protection community" is similar to "minimal population wild plant protection community". , there is no unified method to determine its quantity, location and area in its planning and design, and it is often influenced by factors such as local government, planning and design ideas, and capital investment. There are hundreds of them, and the location and area of ​​nature protection areas are affected by subjective factors, which have a certain degree of randomness. After the planning is completed, the degree of approval is low, and the sustainability of later management and maintenance is not strong; The community is often aimed at areas with better natural environmental conditions, and the protection of the community is not closely related to the biological and ecological characteristics of the target species, and the scientific nature is insufficient.

[0004] There is currently no specific technical method for the determination of the number, location and area of ​​wild plant protection plots with extremely small populations. This method is the first method for determining the number, location and area of ​​wild plant protection plots with very small populations in the planning and construction
