How to calculate the per capita tourism area in the calculation of tourism environmental capacity? Is there a fixed value or different types have different values?

The environmental capacity of scenic spots refers to the capacity of scenic resources owned by scenic spots to tourists within a certain geographical scope. This capacity is inherent in a scenic spot, and it is an important factor to measure the landscape connotation, development value and development prospect of a scenic spot.

Estimation methods of environmental capacity can be divided into area capacity method, swimming capacity method, ecological capacity method and bayonet capacity method.

1, area capacity method

Area-capacity method is related to the types of scenic resources, the size of the interface of scenic resources, the connotation of scenic resources and topography. The larger the scope, the richer the connotation of landscape resources, the more favorable the landform is for development, and the greater the landscape capacity, the smaller it is. The capacity of a scenic spot is the maximum environmental capacity that a scenic spot can reach, which is immutable and can be estimated by technical parameters. This method is suitable for the flat front area, that is, the comprehensive supporting area and the river beach area.

Calculation formula: C = A/a

(c) Reasonable environmental capacity of tourist areas A- Scenic tourist areas, excluding wetlands and surrounding protected areas A- Suitable tourist areas for everyone)

Tourist area (hectare) = total area (hectare) × 30% of tourists.

Environmental capacity (person) = tourist area (hectare)/per capita suitable tourist area (m? /person)

2. Rotating capacity method

The method of tour capacity is related to the nature, length and width of scenic spots roads. This method is suitable for scenic spots with steep terrain and linear layout.

Calculation formula: N = H/A

(n- reasonable capacity h- swimming length a- per capita swimming area)

In the route extrapolation algorithm, the regional tourist capacity takes the per capita unit size index of 5- 10 m? /person.

3. Ecological capacity method

Ecological capacity method is the capacity calculated by planners with ecological pressure index under the reasonable consideration of protecting scenic resources. The estimation of ecological capacity method is influenced by the regional environment of scenic spots, the connotation of scenic resources, ecological indicators and the requirements of planning and management departments for the protection of scenic spots. Ecological pressure refers to the maximum number of tourists allowed in a scenic spot without destroying the ecological environment. The planned ecological pressure index is 1.0-2.0 person/hectare.

Calculation formula: O = S × d

(O- ecological capacity S- directly accessible area D- ecological pressure index)

The directly tourable area of the scenic spot = the total area of the scenic spot × 50%-70%.

(4) bayonet capacity method

The estimation of bayonet capacity method is carried out after the scenic spot planning is completed and the tour mode and tour route organization are determined. The bayonet capacity method is influenced by the landform, tour mode, tour organization and transportation of the scenic spot, and the unit is expressed as "person-time/unit time".
