Ecosystem assessments can be classified into assessment of ecosystem conditions and assessment of ecosystem services. Between the two assessments there are great differences on the content and the methods. The former, developed in the early days of the assessment, emphasizes particularly on the conditions of ecosystem. However, the latter, emerged in the recent years, pays more attention to the value of the ecosystem services. This paper summarizes studies and questions of ecosystems, and discusses issues on the purposes, scales, participants, methods and technology of ecosystem assessments.
