Abstract Similarities and differences of spatial error structures surface precipitation estimated with successive version 6 (V6) 7 (V7) Tropical Rainfall Measuring Mission (TRMM) Multisatellite Precipitation Analysis (TMPA) algorithms are systematically analyzed through comparison the China Meteorological Administration's national daily analysis from June 2008 to May 2011. The TMPA products include V6 V7 real‐time 3B42RTV6 3B42RTV7 research 3B42V6 3B42V7. Both versions outperform their...

Cunninghamia lanceolata (Lamb.) Hook. (Chinese fir) is one of the main timber species in Southern China, which has a wide planting range that accounts for 25% overall afforested area. Moreover, it plays critical role soil and water conservation; however, its suitability subject to climate change. For this study, appropriate distribution area C. was analyzed using MaxEnt model based on CMIP6 data, spanning 2041–2060. The results revealed (1) minimum temperature coldest month (bio6), mean...

Understanding the impact of land use change on ecosystem service values (ESV) will provide a valuable reference for formulation and implementation ecological restoration programs (ERPs) policies. The Guizhou Province is typical karst region with fragile in southwest China. During past decades, multiple ERPs, especially Grain Green Program (GFGP), have been implemented this region, which has resulted dramatic change. However, how ESV responded to remains unclear. Moreover, few studies...

Abstract In this study, we comprehensively analysed daily precipitation time series of 590 rain stations in China covering 1960–2005. Ten indices were defined to evaluate changing patterns regimes and trend detection was performed using Mann–Kendall test linear regressive technique. For the sake better understanding underlying causes behind properties regimes, also investigated spatial temporal variations atmospheric circulation water vapour flux. The results revealed different events across...

The latest Version-7 (V7) Tropical Rainfall Measuring Mission (TRMM) Multi-satellite Precipitation Analysis (TMPA) products were released by the National Aeronautics and Space Administration (NASA) in December of 2012. Their performance on different climatology, locations, precipitation types is great interest to satellite-based community. This paper presents a study TMPA (3B42RT 3B42V7) for an extreme event Beijing its adjacent regions (from 00:00 UTC 21 July 2012 22 2012). Measurements...

Tropical Rainfall Measurement Mission (TRMM) is one of the most popular global high resolution satellite-based precipitation products with a goal measuring over oceans and tropics. However, in recent years, TRMM mission has come to an end. Its successor, Global Precipitation (GPM) was launched measure earth’s structure, aim improve upon project. Both have their own strengths weaknesses resolution, accuracy, availability. The this study evaluate hydrologic utilization GPM humid basin China....

Understanding the driving mechanism of vegetation changes is essential for restoration and management. Vegetation coverage in Poyang Lake basin (PYLB) has changed dramatically under context climate change human activities recent decades. It remains challenging to quantify relative contribution natural anthropogenic factors due their complicated interaction effects. In this study, we selected Normalized Difference Index (NDVI) as an indicator growth used trend analysis Mann-Kendall test...

Carbon storage plays an important role in the global carbon cycle and climate change mitigation. Understanding relationship between land use can significantly contribute to neutrality sustainable development. However, most previous studies only analyze due change, while few quantitatively evaluate contributions of various transitions (LUTs) which cannot provide enough information for management. In context rapid urbanization ecological conservation, Poyang Lake basin (PYLB) has experienced...

In the context of global warming it remains challenging to evaluate declining soil erosion due ecological engineering measures, and isolate quantify contributions various factors involved in erosion. For this study, conservation dynamics Ganjiang River Basin (GRB) southeast China were quantitatively assessed based on Integrated Ecosystem Services Tradeoff Assessment (InVEST) model. Based analysis attribution precipitation Fractional Vegetation Cover (FVC), dominant determined by scenario...

Net Primary Productivity (NPP) is a basis of material and energy flows in terrestrial ecosystems, it also an important component the research on carbon cycle budget. This paper evaluated spatial distribution pattern temporal change trends for forest NPP simulated by LPJ (Lund-Potsdam-Jena) model NDVI (normalized difference vegetation index) Yangtze River basin from 1982 to 2013. The results revealed that: (1) has gradually decreased southeast coast northwest. mid-lower were higher than that...
