We have to face a world of changing climate due to greenhouse gas emission from industrial development. The article summarized the latest observation of the impact of climate change on species in China and emphasized the importance of healthy ecosystem as a basic measure of mitigating the negative impact of and enhancing the adaption to climate change. Based on existing researches，the author concluded that，geographically，the ecosystems in northern and western China are both vulnerable and heavily impacted by climate change. It is suggested that the Qinghai-Tibetan Plateau，the mountains of southwestern China，and the rivers and lakes in western China are the priority conservation areas for better climate adaptation，and should be targeted to no species extinction and no degradation of ecosystem services. To do so，the management of natural resources should be improved，more field researches on and monitoring of the interaction between climate and biodiversity should be carried out. It is also urgent to enhance human capacity and financial resources on climate adaptation.
