Ecosystem long-term observation data product system

Abstract

Ecosystem water 、 soil 、 gas 、 The long-term positioning observation and data accumulation of biological factors can provide scientific basis for ecosystem evaluation and management , However, at present, China has not established a long-term observation data product system of ecosystem , Unable to provide effective guidance for the production of data products . Firstly, the data product system of international ecological environment observation and research network is analyzed , Then combined with the existing ecosystem long-term observation norms and the actual situation of data resources , Product classification based on data 、 The two dimensions of data product classification put forward a set of ecosystem long-term observation data product system . This system can represent the content of long-term observation data products , It can also express the production of data products 、 Processing , It has been applied to China Ecosystem Research Network （CERN） Design of product system for long-term observation data of forest ecosystem . The data product system has good practical value , It plays an important role in improving the use value of long-term observation data .
