( Garrigues, 2008)
Global Remote Sensing LAI product’s accuracy and consistence are not good enough for global ecological and environmental monitoring
It maybe helpful synergize multi-source remote sensing data for global ecosystem and environmental monitoring
Multi-source remote sensing data from different sensors provide a chance to improve the temporal and spatial
resolution of existing hydrological products.

China-ASEAN has become a new engine for world economy. ASEAN mainly includes the Indo-China Peninsula and Malay Archipelago in
the southeast of Asia.
The increasingly acceleratedurbanization, rapid growth ofpopulation and socio-economicdevelopment could cause a seriesof ecological environmentalproblems.
There is hence an urgent need tomonitor the ecologicalenvironment and to cooperate inrespect of environmentalprotection in China-ASEAN.
3.2 Eco-Hydrological Key Parameter Products for China-ASEAN
Fig. 1 Distribution of PAR in China-ASEAN in 2013
The maximum value of PAR in theregion is 3,500 MJ/m2, which islocated on the south slope ofTibetan Plateau with relativelylow latitude and high altitude;and the minimum value is 2,400MJ/m2, which is located inHeilongjiang, the northeast ofChina, with a relatively highlatitude and a low altitude.
As the ASEAN countries are inthe region with low latitude,their annual PARs are close andare generally 3,000 MJ/m2.
Fig. 2 Distribution of annual light-temperature potential productivity in China-ASEAN in 2013
The lowest annual light-temperaturepotential productivity in China-ASEANis on the Tibetan Plateau and thehighest is on Indo-China Peninsula.
It can be above 225 t/hm2 (hm2: hectare)in some areas of Myanmar, Thailand andCambodia on the Indo-China Peninsula,the highest value of the region; theannual light-temperature potentialproductivity at the boundary of thenorthwest part of the Tibetan Plateauand Xinjiang is below 25 t/hm2, thelowest value in the region.
The annual light-temperature potentialproductivity in eastern China presentsthe trend of gradual increase fromnorth to south, and the highest valuecan be up to 50t/hm2.
Fig. 3 Spatial distribution of the evapotranspiration in China-ASEAN
Malaysia in China-ASEAN has the best overallwater conditions, followed by the Indo-ChinaPeninsula. China has the poorest water conditionswhich are extremely uneven in their spatialdistribution.
The area with a tropical rainforest climate inMalay Archipelago has a stable precipitationthroughout the year, while the precipitation inIndo-China Peninsula characterized with tropicalmonsoon climate and tropical savanna climate hasobvious differences in dry and rainy seasons, ofwhich the precipitation in the rainy seasonaccounts for about 70~80% of the annualprecipitation;
the evapotranspiration of each month in the ASEANcountries is above 40 mm and there is no obviousdifference in the dry and rainy seasons.Different climate areas in China arecharacterized with wet/warm and dry/cold seasonsand the precipitation and evapotranspirationreach their peak in June – August in summer.
Malaysia has a tropical rainforest climateand tropical rainforest ecosystem withprecipitation(3,022mm), evapotranspiration(947mm) and water surplus (2,075mm) higherthan those of the Indo-China Peninsula(2,107 mm, 793 mm, 1314 mm).
Under the influence of the temperatecontinental climate, the precipitation(720 mm), evapotranspiration (383 mm) andwater surplus (337 mm) of China are thelowest in the region.
The water deficit area in China-ASEANaccounts for 9% and mainly distributes inthe agricultural areas in north andnorthwest China, the Tibetan Plateau, etc.
