As a wetland of international importance, the ecological function zone of the Sanjiang Plain (EFZSP) plays an important role in maintaining waterfowl habitat. With the increasing disturbance of human beings, land use and climate changes, habitat suitability for waterfowls (HSW) has drawn greater attention of ecologists. In this study, Landsat TM/ETM+/OLI and HJ-1B images in 1990, 2000, 2010 and 2015 were used to obtain land cover classification by object-based image analysis, and the entropy and analytic hierarchy process methods were adopted to determine the factors and their weights, the factors selected in this study included water condition (lake and river density), disturbance factor (residence and road density), shelter condition (land cover type and slope), and food abundance (NDVI).

Optical emission spectroscopy (OES) was used to detect the plasma distribution during the depositing process of diamond films with hot filament chemical vapor deposition (HFCVD) method using acetone as carbon source. The surface and cross section of deposited diamond films were characterized by scanning electron microscopy (SEM) and their quality was tested with Raman spectroscopy. OES results showed that the intensity of active species near the center is higher than that in marginal area in the case of linear array of hot filament.
