Problems solved by technology

However, China started late in the planning and implementation of urban and regional ecological parks, and the existing ecological system is still difficult to meet the needs of the public
In addition, as the level of urbanization continues to increase, the quality of natural habitats is degraded due to human disturbance, which affects the health of urban and regional ecological networks.

Embodiment 1

[0068] Such as figure 1 As shown, the present embodiment provides a method for constructing, evaluating and optimizing a regional ecological network, the method comprising the following steps:

[0069] S1. Build an ecological network.

[0070] From the perspective of landscape ecology, the landscape is a natural complex higher than the ecosystem, and the material cycle and energy exchange of the landscape, that is, the landscape flow, is the decisive factor controlling the stability of the landscape function. The operation of landscape flow must be realized by overcoming certain resistance and manifested in a certain landscape spatial pattern. Therefore, when constructing an ecological network, in order to realize the connection between landscape function and landscape structure, it is necessary to consider the spatial layout of relevant driving and limiting factors based on the needs of different landscape functions, and to quantify the spatial characteristics of functions w...

Embodiment 2

[0129] The construction, evaluation and optimization method of the regional ecological network in this embodiment is verified by taking the construction of the ecological network in the Beijing-Tianjin area as an application example, including the following steps:

[0130] S1. Build an ecological network.

Abstract

The invention discloses a method for constructing, evaluating and optimizing a regional ecological network. The method comprises the following steps of: constructing the regional ecological network; wherein the regional ecological network comprises ecological source land, ecological corridors and ecological nodes; judging whether the regional ecological network conforms to the scale-free network power distribution law or not, and analyzing the regional ecological network to obtain the overall distribution condition of the regional ecological network; and optimizing and adjusting the regional ecological network which does not accord with the scale-free network power distribution law, identifying the non-uniform and blank regions of the ecological corridor and the ecological nodes from the overall distribution condition of the regional ecological network, and optimizing and adjusting the grades and positions of the ecological corridor and the ecological nodes. By constructing an efficient and harmonious regional ecological network, the method is of great significance to improvement of urban and regional ecological environments and realization of sustainable development of cities.

Description

technical field [0001] The invention relates to a construction, evaluation and optimization method of a regional ecological network, which belongs to the fields of landscape ecology and urban ecological planning. Background technique [0002] Since the 1990s, ecological network has become a research hotspot in many fields such as landscape ecology, urban planning and design. With the continuous deepening and integration of the understanding of ecological network in various disciplines, it is gradually recognized that ecological network has multiple functions such as ecology, leisure, aesthetics and landscape. The integrity and continuity of urban and rural natural habitats is an important guarantee for maintaining urban ecological health and improving the urban living environment. The vigorous rise of ecological network planning practices in the world has greatly promoted the construction of regional ecological networks and the development of related technical methods. How...
