Nui Coc Reservoir

The Nui Coc reservoir, Thai Nguyen province was built on the Cong River for multi-purposes of providing water for local people such as agricultural irrigation, aquaculture, tourism activities and especially the drinking water supply for the Thai Nguyen city and other surrounding areas. This paper presents the results of the monthly surveys which were conducted during the year 2011 for determination of diversity of Microcytis and the microcystin contents in the isolated Microcystis strains in the water environment of the Nui Coc reservoir. The present results showed that eight species of Microcytis genus of which Microcystis aeruginosa in the water environment of the Nui Coc reservoir was the most abudance. The Microcystis cell density of the Nui Coc reservoir varied seasonally and the highest values were observed in high temperature in the rainy season. The results from the High-Performance Liquid Chromatography (HPLC) analysis showed that the microcystin contents in the isolated Microcystis strains from the Nui Coc reservoir ranged from 0.116 to 0.40 µg MC/mg dried mass. The high cell density of Microcystis and high microcystin concentrations in the isolated Microcystis strains from the Nui Coc reservoir revealed the potential risk for human health. The results also highlighted that it is very necessary and urgent to carry out regular monitoring programs for detecting the occurrence of cyanobacteria and phytoplankton in the water environment of the Nui Coc reservoir in order to timely warn the potential risk of cyanobacteria boom and the adverse impacts on the aquatic ecosystem and especially on human health.

The multiple cropping index of farmland is a significant characterization of land use intensity. Based on the NDVI data, this paper calculated the multiple cropping index of farmland in China using the S-G filtering method, and proposed an optimized regionalization scheme for the farmland use. The findings reveal that from 2000 to 2018, the multiple cropping index of farmland in China underwent the fluctuation of rising first, then falling and rising continuously, which was closely associated with the agricultural support policies enforced in China. Counties whose multiple cropping indexes decreased from 2009 to 2018 were mainly located in areas primarily producing grain, which exerted a greater influence on food security. The gap between the multiple cropping index and potential multiple cropping index of farmland is increasingly widening from north to south in China. Accordingly, four types of grain producing zones were delineated: key development zone, potential growth zone, appropriate development zone, and restricted development zone. Some suggestions, such as rotation, fallow, determination of yield by water and offsetting the quantity balance of farmland by increasing the multiple cropping index, are put forward based on different zones.
