What are the "three areas" of nature reserves? A. Core area B. Concentration area C. Buffer area D. Reality

The "three areas" of nature reserves refer to the core area, buffer area and experimental area.

The core area refers to the most important and fragile area in the protected area, usually the area where all human activities are prohibited. Buffer refers to a certain area around the core area, which not only restricts human activities, but also provides some protection for the ecological environment of the core area.

Experimental area refers to the area where scientific research, education, tourism, development and other activities are allowed, and it is also an important platform for managing and disseminating the value of protected objects. These three areas are interrelated and mutually restricted, which constitute an important management system of nature reserves.

In the core area, all destructive activities such as logging, gathering and hunting are prohibited. This is because the core area is the most important and fragile area in the nature reserve, and human activities may have a great impact on its ecological environment, and may even lead to the collapse of the natural ecosystem.

Buffer plays a transitional role, which can not only provide a safe line for the core area, but also meet the needs of some people. In the buffer zone, people can usually carry out some moderate activities, such as agriculture, forestry and tourism, but they need to be strictly restricted and supervised.

The experimental area is an important area for the management and monitoring of protected areas. At the same time, it can also play a positive role in strengthening the construction of ecological civilization and the dissemination of protected objects in protected areas through activities such as popular science education, tourism and scientific research.

In addition to the above division of nature reserves, nature reserves have also implemented a series of scientific protection measures in ecological protection. For example, adopt land use methods such as "ecological forest farm" and "ecological pasture" to promote the restoration of vegetation and animals in the reserve; Strengthen soil erosion control to curb the occurrence of land desertification; Establish a biodiversity monitoring and evaluation system to keep abreast of the status quo and changes of natural resources.

Carry out public education and publicity activities to make more people realize the importance of protecting natural resources and take an active part in protection actions. In addition, the managers of nature reserves will formulate specific protection measures according to different geographical and ecological conditions to minimize the impact on the ecological environment.

In a word, the establishment and effective management of nature reserves can not only protect precious biodiversity and rare species, but also improve human living environment, promote sustainable economic development and lay a solid foundation for future sustainable development.
