Abstract
The invention provides a comprehensive evaluation method for ecological land, which can comprehensively analyze and evaluate the ecological land and effectively deal with the ecological space management and control and development process. Can provide basic basis for ecological land management and control, homeland space planning and compilation and the like.
Description
Technical Field
The invention discloses a comprehensive evaluation method for ecological land, belonging to the field of planning and designing methods for ecological land in a homeland space.
Background
At present, the research of ecological space management and control planning is still in a starting exploration stage, and the project research and planning practice based on the ecological space management and control aspect are less, and a mature planning research method system is lacked. Therefore, the invention provides a comprehensive evaluation method for ecological land for supporting ecological space assessment and ecological space management and control system based on national policies and urban development requirements and reconstructing ecological management and control planning research.
Disclosure of Invention
The invention aims to provide a comprehensive evaluation method for ecological land for supporting an ecological space evaluation and ecological space management and control system.
In order to achieve the purpose, the technical scheme of the invention is as follows: a comprehensive evaluation method for ecological land is characterized by comprising the following steps
A. Four major sensitivity factors were determined: landform sensitivity factors, water ecology sensitivity factors, biological protection sensitivity factors and natural disaster sensitivity factors; wherein, the landform sensitivity factors comprise three factors of elevation, gradient and vegetation coverage which are respectively marked as a1, a2 and a3, and the weights thereof are respectively marked as b1, b2 and b 3; the water ecological susceptibility factors comprise three factors of catchment corridor, current water system, ecological protection and ecological red line which are respectively marked as a4, a5 and a6, and the weights thereof are respectively marked as b4, b5 and b 6; the susceptibility factor of the biological protection is marked as a7, and the weight thereof is marked as b 7; the natural disaster susceptibility factors comprise two factors of land utilization and geological disaster susceptibility degree which are respectively marked as a8 and a9, and the weights thereof are respectively marked as b8 and b 9;
B. three interference factors are determined: traffic facility interference factors, municipal facility interference factors, landscape recreation interference factors; wherein the interference factors of the traffic facilities comprise three types of highways, main roads and railways which are respectively marked as c1, c2 and c3, and the weights thereof are respectively marked as d1, d2 and d 3; the municipal facility interference factors comprise a sewage plant and a transformer substation which are respectively marked as c4 and c5, and the weights thereof are respectively marked as d4 and d 5; the landscape rest interference factors comprise a human character class and a natural class which are respectively marked as c6 and c7, and the weights thereof are respectively marked as d6 and d 7;
C. ecological sensitivity analysis, four sensitivity factors are considered: coupling the landform sensitivity factor, the water ecological sensitivity factor, the biological protection sensitivity factor and the natural disaster sensitivity factor, and determining the result of the ecological sensitivity analysis as follows:
S1=ai*bi，(i=1~9)；
D. ecological interference analysis, three interference factors are considered: the interference factors of the traffic facilities, the interference factors of the municipal facilities and the interference factors of the landscape recreation are coupled, and the ecological interference analysis result is determined as follows:
