During the past five decades, intensive
exploitation of water resources, mainly by agricultural water
consumption, has resulted in changes of the temporal and spatial
distribution of water resources and has caused serious environmental
problems in the Tarim River Basin. The ecosystems and the ecological
processes dominated by natural vegetation are seriously impacted by
water diversion for irrigation purposes. The SuMaRiO project
(Sustainable Management of River Oases along the Tarim River in China)
aims at sustainable land management practices that explicitly take
into account ecosystem services (ESS) and ecosystem functions (ESF).
For sustainable land use along the river oases of the Tarim, the
mutual relations between the ESS and the ESF in the upper reaches
(e.g. production function) and in the lower reaches (e.g. habitat or
regulatory function) must be known. In order to assess the effects of
the conducted government's restoration campaign as well as the impact
of climate change on floodplain forests the local stakeholders
requiere a solid monitoring plan.
The proposed project will develop a remote sensing based change detection method for long-term monitoring of floodplain forests along the Tarim. Based on multitemporal RapidEye data we try to determine the optimum period for vegetation type and degradation recognition. For this purpose we will build a spectral library of different phenological and degradation stages. Ideally will the library information be transferable to other imagery recording dates and neighboring forest areas. During the phenological year the spectral signatures of important indicator species (Populus Euphratica, Tamarix ......,) will be compared to the actual field conditions. It is assumed that a high class depth and class accuracy can be achieved.
In addition will structural indices (leaf area index, plant coverage, avg. habitat size, number of habitats, habitat networks) be developed that are appropriate for the diagnosis of forest conditions and support the long-term monitoring of floodplain vegetation and the assessment of the ESS / ESF. The method described allows upscaling from the local to regional scale (1:25.000) and thus creates an efficient use of remote sensing data and a basis for the monitoring plan.
