High and cold grassland ecosystem health assessment and early warning platform construction method

Abstract

The invention discloses an alpine grassland ecosystem health assessment and early warning platform construction method. The method comprises the steps that alpine grassland fragile ecosystem health assessment is carried out; building a future scene of the fragile ecosystem of the alpine grassland, and simulating main ecological elements; and constructing an alpine grassland fragile alpine grassland ecosystem health assessment and early warning platform. According to the method, ecological system health assessment and early warning are realized, so that scientific and reasonable decision support is provided to formulate targeted precise intervention measures, and the overall scheme and countermeasures of comprehensive ecological environment management are more scientific, regionalized and specific.

Description

technical field [0001] The invention relates to ecosystem technology, in particular to a method for constructing a typical fragile alpine grassland ecosystem health assessment and early warning platform. Background technique [0002] Different regions have their own unique ecological characteristics and major ecological and environmental problems. How to scientifically screen out the early warning indicators of regional typical fragile ecosystems and determine their thresholds more accurately is the main problem facing the current regional ecosystem security early warning. [0003] At present, a lot of research has been done at home and abroad on the basic principles and methods of ecological security early warning, ecosystem health concepts and evaluation methods, ecosystem risk assessment applications and early warning characteristics, etc. Service modeling, ecological compensation system, ecological red line, etc. However, the internal structure and process of different ...

AI Technical Summary

Problems solved by technology

By systematically sorting out the existing ecosystem health assessment methods and early warning technologies, and comprehensively analyzing the main technical methods, intellectual property rights and technical standards involved in the current ecosystem health assessment and risk early warning, it is found that these technologies and standards are still used in the application of fragile ecosystems in Gansu. There are some problems: there are huge differences in the evaluation models and evaluation systems of different ecosystems

Although there have been many achievements in relevant patent authorization and standard formulation, there are generally problems that are difficult to promote and replicate; from the perspective of the achievements themselves, the evaluation of ecosystem health is highly subjective and difficult to continuously track and predict; for indicators There are still some differences in the selection and quantification and the assignment of weights
