The invention is called future climate change impact on biodiversity and comprehensive risk assessment technology, which belongs to the technical field of ecological environment protection and climate change response. Based on the comprehensive investigation of the characteristics of biodiversity in my country, the climate change scenario prediction technology, Monte Carlo method, computer simulation, GIS and risk assessment technology, as well as theories and practices of climatology, probability theory, etc., are used to establish climate change response. Biodiversity impact and risk assessment indicators and species distribution loss rules, randomized climate scenarios, combination of niche models and climate scenarios, simulation of climate change impacts, and assessment of climate change impacts and risks on biodiversity. In order to establish technical countermeasures for biodiversity conservation and adaptation to climate change, effective conservation of biodiversity can play important social, economic and environmental benefits. These technologies are highly operable, low in cost, low in maintenance, and widely applicable, especially for assessing the impact and risk of climate change on my country's biodiversity.
