FromVulnerabilitytoRisk從脆弱性到風(fēng)險(xiǎn)RiskAssessmentMethodology:風(fēng)險(xiǎn)評(píng)估措施學(xué)簡(jiǎn)介AnIntroductionTuesday,07thJune2023VulnerabilityVulnerabilityisafunctionofthecharacter,magnitudeandrateofclimatevariationtowhichasystemisexposed,itssensitivitytothosevariationsanditsadaptivecapacity.

脆弱性:用來(lái)描述系統(tǒng)暴露于氣候變化下旳特征,尺度和概率,也涉及系統(tǒng)對(duì)于氣候變化旳敏感度和適應(yīng)能力.

System

系統(tǒng)–個(gè)人,戶(hù),小區(qū),市區(qū),基礎(chǔ)設(shè)施,經(jīng)濟(jì)部門(mén),生態(tài)系統(tǒng),省,國(guó)家.
