Seven key technical methods of Urban Ecological Planning: Other Methods

In addition to the five methods mentioned above, some other theoretical methods will be used in ecological planning. Here we will introduce them one by one.

 

1. Similarity Analysis Method

When there is uncertainty in Urban Ecological Planning and Construction, similarity analysis can be used to solve such problems.

Learning from the development experience and environmental protection experience of similar areas is an important task in ecological capacity building. The similarity analysis method is applicable to planning with great uncertainty, strategic emphasis, and strong Macro. For example, the urban ecological planning method is particularly applicable to the dynamic interaction process of social and economic development planning and environmental protection planning. The advantage is that it is intuitive, has a good image, is simple, and easy to operate. Similarity analysis can be said to be an empirical decision-making method, therefore, quantitative and qualitative analysis should be carried out on the basis of a large amount of comprehensive experience, to find out the law, and to strictly determine its similarity, so as to improve the accuracy and certainty of decision-making and prediction.

Similar analysis plays a major role in solving risks and uncertainties. This method is especially suitable for macro-level analysis and helps to grasp future trends and development directions of the region, this makes the plan more strategic.

In practice, for example, to conduct environmental planning for a city, select a city or region with similar characteristics for Similarity comparison, such cities or regions with similar characteristics can be strategic, industrial, layout, and geographical similarity. Then, we can analyze the environmental protection policies and effects of these cities and learn about their development experience, take its essence and follow its laws, so as to provide a basis and reference for formulating planning and strategies. From the beginning, we are all determined by the fact that similar conditions and environments often produce similar results. This is the value of Similarity analysis.

 

2. Energy Analysis

The energy theory provides a new way of quantitative analysis for ecological research.

The definition of value can include the sum of energy formed and invested in products or economic activities. Any product or service can be quantitatively described by value, it can represent any ability to do work as a unified unit of solar power. The energy value can be linked by the energy conversion rate and efficiency, and can be used to measure all the wealth created by the natural resource environment and human social economy, that is, the real value of a thing depends on the amount of solar energy it contains. Value can quantitatively analyze the real value of resource, environment, and economic activities. In ecological planning, we can use its theories and methods to formulate correct economic development policies and implement sustainable development strategies, this is of great practical significance.

 

3. Information entropy analysis

Information entropy can be used to express the disorder and disorder of any system or material movement. The introduction of information entropy can quantitatively determine the evolution direction of the urban system. At the same time, the multidimensional information in the system can be quantified and integrated through information entropy derivation, and the evaluation score based on the relative superiority of information entropy is calculated. The larger the value, the better the status of the ecosystem.

The Evolution and changes of the urban ecosystem under the influence of external disturbance and internal fluctuations fully conform to the predefined assumptions of the dissipation structure system. Therefore, the concept of information entropy can be used to describe its evolution characteristics and serve as the basis and basis for Urban Ecological Planning.

 

4. Dynamic Analysis

The urban ecosystem is dynamic and periodic.

In cities, both environmental problems and socio-economic conditions will change with time, and planning must be able to respond quickly and be updated. Therefore, dynamic analysis is applied in Urban Ecological Planning, A rolling urban ecological planning management system can be established in terms of Theories, Methods, work procedures, and tools to adapt to the continuous updating and adjustment of the planning, which is of practical significance in the planning.

 

5. Life Index Evaluation Method

A city is a man-made, natural-social-economic, and highly composite ecosystem.

The city vitality index is generally explained in four aspects: Productivity, lifestyle, ecological potential, and vitality. That is, starting from the sub-system, the development trend of the urban economic sub-system, social sub-system, and natural sub-system is expressed by productivity, living state, and ecological trend respectively, the degree of vitality is used to characterize the coordination between subsystems.

 

6. Geographic Information System Technology

GIS is widely used in resource and environment evaluation management, urban and regional planning and management, and many other fields. Urban Ecological Planning often evaluates the sensitivity of the regional ecological environment, the ecological system service function, and the ecological suitability, and implements them to specific spaces. GIS can easily complete the above work. He provided powerful tools for urban ecological planning and promoted the further development of urban ecological planning.
