“…Večina tovrstnih hidroloških metod temelji na analizi mesečnih podatkovnih nizov, kot npr. RVA (Range of Variability Approach) in ABF (Aquatic Base Flow) metode (RichTer et al, 1997;Eisele et al, 2003), manj pogosti pa so pristopi ocenjevanja na letni ravni, ki je časov-ni okvir ocenjevanja količinskega stanja voda po okvirni direktivi o vodah. Za oceno pretoka, ki je potreben za ohranjanje dobrega ekološkega stanja površinskih voda na letni ravni smo uporabili nemški vodnobilančni pristop s scenarijem petih sušnih let v zadnjem tridesetletnem obdobju (SchlüTer, 2006).…”

IzvlečekDoločitev razpoložljivih količin podzemnih voda je osnovnega pomena za njihovo trajnostno rabo. Sodobni pristopi ocene razpoložljivosti podzemnih voda celovito obravnavajo posledice odvzemov podzemne vode, vključno z vplivi na ekosisteme in ekološko stanje površinskih voda. Vodno telo podzemne vode je v dobrem količinskem stanju, če odvzemi podzemne vode ne povzročajo pomembnih poškodb ekosistemov, odvisnih od podzemne vode, in ne slabšajo ekološkega stanja površinskih voda. V članku predstavljeno metodologijo smo razvili kot sestavni del ocene količinskega stanja vodnih teles podzemne vode v Sloveniji in je prilagojena lastnostim obravnavanih ekosistemov ter hidrološkim in hidrogeološkim značilnostim slovenskega ozemlja. Uporabili smo dva različna pristopa ocene potrebnih količin podzemnih voda za ohranjanje gozdnih habitatov na aluvialnih vodonosnikih in habitatov dvoživk ter mehkužcev na kraških območjih. Oceno smo izvedli na ravni vodnih teles podzemne vode in letnih povprečij časovnih spremenljivk vodne bilance, izračunanih z regionalnim vodnobilančnim modelom GROWA-SI. Na območjih vodnih teles podzemne vode, kjer so prisotni obravnavani ekosistemi, znaša ta količina od 0,1 % do 12,4 % obnovljivih količin podzemnih voda. Ocenjeni delež letnih obnovljivih količin podzemnih voda, potrebnih za ohranjanje ekološkega stanja površinskih voda je za celotno območje Slovenije 23,2 %. Največji delež je na območju severovzhodne Slovenije, kjer dosega 30 %, najmanjši pa v vzhodnih Alpah, Karavankah in Kamniško-Savinjskih Alpah s 16,6 % povprečnih letnih obnovljivih količin. AbstractAssessment of the available quantity of groundwater is of essential importance for its sustainable use. Modern approaches for estimation of groundwater availability take into account all potential impacts of abstractions, including impacts on groundwater dependent ecosystems and impacts on surface waters ecological status. Groundwater body is in good quantitative status if groundwater abstractions do not cause significant damages to groundwater dependent ecosystems and significant diminution in the ecological status of surface water bodies. The methodology presented in this paper was developed as an integral part of the assessment of the quantitative status of groundwater bodies in Slovenia and is tailored to the characteristics of the groundwater dependent ecosystems as well as hydrological and hydrogeological conditions in the Slovenian territory. Two different approaches were implemented; for forest habitats on alluvial aquifers, and habitats of amphibians and molluscs in karst areas. Estimates of the required quantity of groundwater for groundwater dependent ecosystems conservation were performed at the level of groundwater bodies and annual averages of temporal variables of the water balance, calculated with the regional water balance model GROWA-SI. In the areas of groundwater bodies with groundwater dependent ecosystems estimated quantity present 0.1 % -12.4 % of the groundwater recharge. The estimated share of annual renewabl...

“…The ecological status of surface water is here defined by biological, chemical, morphological and hydrological criteria (Eisele et al, 2003). The WFD calls for combined management of surface water and groundwater, with proper assessment of the influence on groundwater quantity and quality of surface water ecology.…”

“…Eco-environmental evaluation was developed in the 1960s as a means of quantitatively and qualitatively assessing the environmental situation (Eisele et al, 2003). Eco-environmental evaluation can provide basic data and information for sustainable development in typical zones (Popp et al, 2000;Linder et al, 2010), such as urban areas (Ng and Obbard, 2005) and mountain zones (Eisele et al, 2003;Isidori et al, 2004). In recent years, considerable interests have focused on identifying if, where and how ecosystem vulnerability is affected by human or natural disturbances (Linder et al, 2010;Chmura et al, 2011).…”

Spatial patterns of ecosystem vulnerability changes during 2001–2011 in the three-river source region of the Qinghai-Tibetan Plateau, China

The three-river source region (TRSR, including Yangtze, Yellow and Lancang rivers), located in the Qinghai-Tibetan Plateau, China, is a typical alpine zone with apparent ecosystem vulnerability and sensitivity. In this paper, we introduced many interdisciplinary factors, such as landscape pattern indices (Shannon diversity index and Shannon evenness index) and extreme climate factors (number of extreme high temperature days, number of extreme low temperature days, and number of extreme precipitation days), to establish a new model for evaluating the spatial patterns of ecosystem vulnerability changes in the TRSR. The change intensity (CI) of ecosystem vulnerability was also analyzed. The results showed that the established evaluation model was effective and the ecosystem vulnerability in the whole study area was intensive. During the study period of 2001-2011, there was a slight degradation in the eco-environmental quality. The Yellow River source region had the best eco-environmental quality, while the Yangtze River source region had the worst one. In addition, the zones dominated by deserts were the most severely deteriorated areas and the eco-environmental quality of the zones occupied by evergreen coniferous forests showed a better change. Furthermore, the larger the change rates of the climate factors (accumulative temperature of ≥10°C and annual average precipitation) are, the more intensive the CI of ecosystem vulnerability is. This study would provide a scientific basis for the eco-environmental protection and restoration in the TRSR.
