Problems solved by technology
In view of the structural characteristics of urban-rural duality in Chinese cities, the current measurement methods for urban greenhouse gas emissions only consider energy processes, carbon sink processes, and industrial processes, ignoring the measurement of greenhouse gas emissions from agricultural and animal husbandry processes and wetland processes.
In addition, the waste disposal process, as the last link of the urban artificial ecosystem, plays an important role in the material cycle, but the current measurement method lacks the measurement of greenhouse gas emissions in this process
[0004] Chinese invention CN201110179588.8 discloses a system and method for measuring greenhouse gases, using 20 minutes as a quantitative pumping cycle, the pumping cycle is not combined with the detected air quality, and the detection is not flexible enough

Embodiment Construction
[0022] The above and other technical features and advantages of the present invention will be described in more detail below in conjunction with the accompanying drawings.
[0023] see figure 1 As shown, it is a flow chart of the carbon sink measurement method for park green spaces. The current urban greenhouse gas emission measurement method only pays attention to the calculation of energy consumption process, carbon sink process and industrial process greenhouse gas emission. The present invention combines urban and rural dualization of Chinese cities Structural characteristics and the importance of waste disposal processes in urban ecosystems, adding agricultural and animal husbandry processes, wetland processes, and waste disposal processes as measurement scopes, provide a method for measuring greenhouse gas emissions in Chinese cities from the perspective of producers. In order to improve the measurement method of China's urban greenhouse gas emissions, the following tech...

The invention relates to a garden green-land carbon sinking capacity detecting system based on automatic sampling analysis. The detecting system comprises a main body, an atmosphere detecting unit, a central controller and a hoop belt, wherein the atmosphere detecting unit is internally provided with a vacuum cavity and is externally connected with a gas storing cylinder and a gas pump for generating negative pressure or compressed gas; the central controller judges a detection result C and calculating a sampling period T (in hours), when C is less than or equal to C1, T=T0; when C is larger than C1, T=T0 / (1+lnC-lnC1), wherein each of T0 and C1is a constant larger than 0, and the central controller records C and T detected at every time; the atmosphere detecting unit and the central controller are arranged inside the body; and the hoop belt is provided with a pull belt capable of achieving pulling and locking functions.
Description
technical field [0001] The invention relates to an atmosphere detection system, in particular to a detection system capable of automatically sampling and intelligently analyzing the atmosphere at any position. Background technique [0002] Cities are the main contributors to greenhouse gas emissions. More than 50% of the world's population lives in cities, and urban residents contribute as much as 67%-80% to anthropogenic greenhouse gas emissions. As the global urbanization process continues to accelerate, the proportion of urban greenhouse gas emissions will continue to rise. Therefore, the control of greenhouse gas emissions from the city level has gradually attracted people's attention. As the main part of the city, the community is the main carrier of various types of land and buildings such as urban residence, public facilities, and transportation. The low-carbon concept is decomposed and refined into the community. Comprehensive measures can support the construction ...
