Construction of integrated ecosystem assessment method at the small-scale intertidal ecosystem based on remote sensing

An integrated ecosystem assessment method based on remote sensing technology at the small-scale intertidal ecosystem was proposed by integrating the ecosystem structure, quality and service function. The method solved the problem of scale conversion and weak systematic in ecosystem assessment. Taking Shuangtaizi estuary of Liaoning Province as the study area, the proposed method was used to assess the status and changing trend from 1990 to 2016. The results showed that the study area was dominated by poor and intermediate grade, 13.1% of pixels showed the significant weakening trend while 6.9% showed the significant growth trend. As a result, the assessment can reflect the spatial and temporal differences of the various land cover types quantitatively, which met beneficiary's experience and consistent with the previous research results. Therefore, the above conclusion showed that the constructed integrated ecosystem assessment method had the feasibility and application potential. © 2018, Editorial Board of China Environmental Science.
