Severe mosaic disease was observed on Iris ensata Thunb. in Spring 2008, in Hangzhou, China and it was found to be widely distributed in that region. Detection of viruses by electron microscopy resulted in the occurrence of a potyvirus in most symptomatic seedlings. Sequencing 1745 nucleotides of the 3'-terminal region of the genome of the typical viral(More)
Air-quality forecasting in urban areas is difficult because of the uncertainties in describing both the emission and meteorological fields. The use of incomplete information in the training phase restricts practical air-quality forecasting. In this paper, we propose a hybrid artificial neural network and a hybrid support vector machine, which effectively(More)
Coastal marsh habitats are impacted by many factors or disturbances, including habitat destruction, pollution, and the introduction of invasive species. Spartina alterniflora (S. alterniflora) is an important invasive species, accounting for a significant proportion of the invasive plants spread around the world. Salt stress is a major environmental stress(More)
Northwest Shanxi is located on the farming-pastoral ecotone of northern China, where aeolian desertification is one of the most serious environmental and socioeconomic issues. The remote sensing image and geostatistical approach were implemented to estimate aeolian desertified land (ADL) dynamic variations from 1975 to 2015. Results showed that the ADL(More)
Aeolian desertification is one of the serious environmental issues in North Shanxi Province. Accurately assessing aeolian desertification dynamics and its causes is essential to formulate an effective strategy for combating aeolian desertification. Here, we adopted remote sensing (RS) images from four periods (1975, 1990, 2000, and 2015) to classify the(More)
Due to the significance of karst groundwater for water supply in arid and semi-arid regions, the characteristics of the karst groundwater flow system in the Liulin spring area, North China, are analysed through isotopic tracing (δ(2)H, δ(18)O, δ(13)C and (3)H) and dating approaches ((14)C). The results show that the primary recharge source of karst(More)
