Résumé partiel
Desert shrub is an important component of the fragile ecosystem in arid and semi-arid regions.The biomass is an important indicator for the study of the structure and function of desert ecosystem.However,the traditional methods of measurement are mostly artificial plots or quadrat surveys,which are mainly destructive measurement.The advantage is that the measurement method is simple and direct.The disadvantage is that it is difficult to obtain the tree related factors of shrub biomass.At the same time,it must harvest the whole shrub,which can’t carry out continuous observation of the same shrub.It also has a certain destructive effect on the fragile desert shrub ecosystem.Therefore,the traditional measurement method has become one of the main constraints of shrub biomass modeling,especially in the large spatial and temporal scale to monitor the shrub biomass.It needs to carry out a large number of Wild Shrubs.The limitations of traditional methods are more significant.In order to realize the real-time,non-destructive and rapid estimation of the aboveground biomass of desert shrubs,the experimental samples were constructed that was based on the traditional biomass modeling method.By means of the image of shrubs in the study area by smart phone shooting method,combining image processing and analysis and according to the characteristics of shrub,a new variable of shrub image area(S)was introduced to build biomass model.By using the technology of mechanical design and manufacture,a field measuring device for the aboveground biomass of desert shrubs was manufactured.Integrated application of digital image processing algorithm and based on the Android platform,the non-destructive and rapid estimation software for the aboveground biomass of desert shrubs was developed
