Assessing the contribution rates of climate change and human activities to runoff in source area Yellow River can provide support for water management Basin. This paper firstly uses a multiple linear regression method evaluate vegetation River. Next, Budyko hypothesis calculate climatic factors (including precipitation, potential evaporation, subsequent changes) changes caused by Tangnaihai Hydrometric Station. The results showed that: (1) annual precipitation have downward trend, while...

Previous studies mainly focused on quantifying the contribution rate of different factors annual runoff variation in source region Yellow River (SRYR), while there are few seasonal variation. In this study, monthly water storage and actual evaporation SRYR were calculated by ABCD model, then a Budyko frame was constructed. Finally, climatic anthropic Tangnaihai hydrological station quantitatively calculated. It turned out that: (1) The changing point data at is 1989. (2) model could well...

Sudden flood disasters cause serious damage to agricultural production. Rapidly extracting information such as the flooding extent of land and capturing influence on crops provides important guidelines for estimating flood-affected area, promoting post-disaster farmland restoration, providing an auxiliary decision-making basis prevention disaster relief departments. Taking event in Henan Shanxi Provinces example, based characteristics variations radar data optical before after disaster, we...

Land-use change has a great impact on regional ecosystem balance and carbon storage, so it is of significance to study future land-use types storage in region optimize the structure. Based existing data different scenarios shared socioeconomic pathway representative concentration (SSP-RCP) provided by CMIP6, this used PLUS model predict land use InVEST area historical period under future. The results show following: (1) will lead storage. From 2000 2020, conversion cultivated construction...

Bosten Lake is an important region of Northwest China that has transformed from a freshwater lake to saltwater since the 1970s. The water quality in basin for social and economic development, nitrogen (N) phosphorus (P) are key indicators quality. land use data, precipitation data Digital Elevation Model (DEM) with Integrated Valuation Ecosystem Services Tradeoffs (InVEST) model were used simulate N P exports basin. spatial temporal dynamics exports, response change analyzed between 2000...

Based on the Lancang River Basin (LRB) hydro–meteorological data from 1961 to 2015, this study uses Mann–Kendall trend test and mutation analyze of variables, as well which year runoff series changes, respectively. We applied Choudhury–Yang equation calculate climate catchment landscape elasticity runoff. Then we quantified impact change human activities change. The results show that: (1) mean annual precipitation (P) in LRB showed an insignificant decline, potential evapotranspiration (E0)...

Analyzing the temporal variation of runoff and vegetation quantifying impact anthropic factors climate change on in source area Yangtze River (SAYR), is great significance for scientific response to ecological protection region. Therefore, Budyko hypothesis method multiple linear regression were used quantitatively calculate contribution rates SAYR. It was found that: (1) The runoff, NDVI, precipitation, potential evaporation SAYR from 1982 2016 all showed an increasing trend. (2) mutation...

The middle reaches of the Yellow River (MRYR) are a key area for carrying out China’s vegetation restoration project. However, impact variation on runoff in MRYR is still unclear. For quantitatively evaluating contribution rate to MRYR, this paper quantified relationship between Normalized Difference Vegetation Index (NDVI) and Budyko parameters (w). Then, we used multiple linear regression calculate different factors variation. Finally, an adjusted formula was constructed influence runoff....

The Lancang River Basin (LCRB) is the largest international river in Southeast Asia, and any change its streamflow, i.e., due to ecological environment runoff, may lead disputes between countries a certain extent. However, impact of vegetation on streamflow LCRB needs be clarified. To assess LCRB, functional relationship Budyko parameter (ω) Normalized Difference Vegetation Index (NDVI) was first computed for constructing modified formula. Finally, we quantitatively estimated influence...
