Problems solved by technology

[0003] At present, most of the evaluation systems for the health of urban ecosystems are constructed from the various elements contained in the urban ecosystem. Although these indicators comprehensively consider many factors such as society, economy, and nature, these methods ignore the relationship between indicators of different properties. Integrating them rigidly based on differences will have a certain impact on the scientific nature of urban ecosystem health assessment
The disadvantage of these methods is that real-time data of each health indicator in the urban ecosystem cannot be monitored in real time, its change trend cannot be predicted, and the structural and functional characteristics of the urban ecosystem cannot be fundamentally revealed.

Embodiment 1

[0030] Such as figure 1 As shown, it is a schematic diagram of the urban ecological system health diagnosis system, and the urban ecological system health diagnosis system includes: a real-time monitoring system 1 and a system control terminal 2, both of which are connected by wireless communication to achieve a good communication effect.

[0031] The real-time monitoring system 1 includes: a data acquisition module 11 , a data transmission module 12 , a data storage module 13 and a data processing module 14 . Real-time monitoring and collection of health index data in the urban ecosystem is carried out through the data collection module 11. The health index data can be roughly divided into five categories: "vitality", "organizational structure", "resilience", " Service function" and "environmental effect", these five categories can also be subdivided into many small indicators, such as: diversity index, environmental load rate, output-input ratio, etc. The type of data coll...

Embodiment 2

[0038] On the basis of the above embodiments, the inventors have found through research that the health index data "diversity index" is closely related to the good air quality rate, x represents the air quality good rate, and y represents the diversity index , there is the following relationship between them:

[0039]

[0040] is the round up symbol, for example

[0041] The measurement of the diversity index is generally cumbersome, and the collection and classification of species types need to consume a lot of time, manpower, material resources and financial resources. The quality of the environment on which each organism depends directly affects the survival and reproduction of the species, so the inventor put the two indicators of the diversity index and the air quality rate together, which is efficient and practical.

[0042] When the number of good air quality days in a quarter or year is known, the corresponding good air quality rate can be obtained. Through the...

Embodiment 3

[0045] Based on the classic evaluation elements of urban ecosystem health, combined with the characteristics of urban ecosystem and emergy analysis, five elements of vitality, organizational structure, resilience, maintenance of service functions, and environmental effects are selected as the evaluation framework. According to the basic procedure of emergy analysis, the emergy analysis is carried out on the urban ecological system, and the emergy index system is obtained. Combined with index correlation analysis and subjective experience judgment, the appropriate emergy indicators were selected and incorporated into the established urban ecosystem health evaluation framework to form the urban ecosystem health emergy index (Table 1). The index is divided into target layer, element layer, and indicator layer, consisting of 5 categories and 17 indicators.

Abstract

The invention discloses an urban ecosystem health diagnosis system, which comprises a real-time monitoring system and a system control terminal, wherein the real-time monitoring system is used for detecting, acquiring, transmitting, storing and analyzing real-time data; the system control terminal is used for displaying data changes and regulating the whole system; and the real-time monitoring system and the system control terminal are in wired/wireless communication connection, the urban ecosystem can be monitored in real time through the system, the health condition can be analyzed and diagnosed, and thus, timely control can be carried out conveniently. The system has the beneficial effects that the real-time data of each health index in the urban ecosystem can be monitored, the change trend can be predicted, the structure and the function features of the urban ecosystem can be disclosed basically, coordination and control in all aspects on the whole system can be realized, and the integrity is high.

Description

technical field [0001] The invention belongs to the field of urban ecological evaluation, planning and management, and in particular relates to an urban ecological system health diagnosis system. Background technique [0002] The city has always been the main creator, owner and consumer of wealth in human society. It is not only the main place for human survival, but also an important base for human development. After the industrial revolution, the city has become the political center, economic center, technology center, information center, cultural center, etc. of the region. There is no doubt that cities play an irreplaceable role in promoting the progress of human society, and maintaining the health of urban ecosystems plays an irreplaceable role in realizing the progress of human society and is crucial to the sustainable development of human society. However, with the rapid economic growth in the process of urbanization, high industrialization, large-scale resource cons...
