Comparison of the Composition, Population Density, and Diversity of the Soil Seed Bank and Standing Vegetation in Deciduous and Coniferous Forests in Korea
No full textTo determine the characteristics of a soil seed bank in a temperate forest, the composition, population density, and diversity of plant species in the soil seed bank, the similarity between the standing vegetation and the soil seed bank and the correlation between the soil seed bank and soil environmental factors (geographic and soil characteristics) that affect the species characteristics of the soil seed bank were investigated in Korean red pine (coniferous) and Mongolian oak (deciduous) forests, which represent the types of forests in Korea. There was no statistically significant difference in the population density and diversity of the species of soil seed bank between the two types of forests. A similarity in the species composition between the standing vegetation and the soil seed bank was found and was higher in the shrub layer than in the canopy and understory layers. The species characteristics of the soil seed bank, such as the species composition and the species diversity, seemed to be more relevant for the herbaceous plants in the shrub layer than for the dominant tree species in the canopy layer. The number of plant species and the population density of the species of the soil seed bank were considered to be affected by the organic content in the surface soil of the forests
Comparing Water Quantity between Korean and Japanese River
No full textTwo watersheds with similar area were selected to compare water qualities between Korea and Japan. The one from Korea is called the Yongdam dam watershed in the Geum river basin, and the other from Japan is called the Nakama watershed in the Onga river basin. The 2 water quality stations from Korea and 2 stations from Japan within each watershed were selected and water quality concentration data were collected to determine load durations, respectively. The relationships between discharge and water pollution load on BOD, COD, SS, TN, and TP were derived, and water pollution loads were estimated on a daily basis in each water quality station. And means of LDCs in each country were drawn and compared with each other. Summarizing the estimated daily water pollution loads and the results of LDCs, it was concluded that TMDL showed 1.49 times higher BOD, 1.11 times higher COD, 4.95 times higher SS, 1.43 times higher TN in Korean and the same TP, and 1st load in LDC showed 1.81 to 6.14 times higher in Korean, and remaining 95th, 185th, 275th, and 285th loads in LDC showed 1.30 to 15.43 times higher in Japanese. Specific loads were expressed with daily mean in the period of each flow duration interval, and were compared with each other between Korea and Japan, of which results were shown with 1.836~8.063 times higher to Korea in high flows, and with 1.119~8.169 times higher to Japan in other flows except SS, TN values in moist conditions. Comparing an annual sum, BOD load was 1.16 times higher in Korea, COD 1.113 in Korea, SS 4.891 in Korea, TN 1.446 in Korea, and TP was same. Evaluating with 10 year frequency, Korea showed 1.041~2.360 times higher loads than Japan except TP in high flows, Japan 1.175~14.226 times higher than Korea except TN in low flows. Annual sum showed that BOD load was 1.517 times higher in Japan, COD 1.564 in Japan, SS 1.408 in Korea, TN 1.008 in Korea, and TP 2.383 in Japan. From the above result, it was concluded that Korean river was getting more water pollution loads than Japanese river in high flow interval, but in other flow interval was higher to Japan in general
Temporal and Spatial Variations of Vegetation Response to Dynamic Change of Meteorological Factors and Groundwater in the Heihe River Basin, China
No full textThe interaction of meteorological factors and groundwater depth affects vegetation coverage and growth, particularly in semi–arid regions where groundwater is extracted for human use. This paper analyzed the characteristics of temporal and spatial variations in the Normalized Difference Vegetation Index (NDVI) between 1998 and 2008 to clarify the response of NDVI to variations in meteorological factors and groundwater depth in the Heihe River Basin, China. The results indicated that: (1) there was a statistically significant response of NDVI to temperature variation, and this was greater than the response to precipitation. Partial years showed a time–lag in response to temperature and precipitation, and NDVI–temperature had a faster response time than NDVI–precipitation. (2) Groundwater depth less than 7.3 m had the greatest effect on NDVI. Salinization, the capillary height and the maximum vegetation root zone were the main factors to increase or reduce the growth of vegetation. The relationship between NDVI and groundwater depth could be fitted with a logistic correlation curve

Occurrence of Weed Species in Pear Orchards in Chungnam Province of Korea
No full textA survey of weed occurrence was conducted to identify noxious weed species in pear orchards to obtain basic information for effective weed control. The survey was conducted in pear orchards situated in Chungnam province of Korea from April to June 2015, for spring, and from September to October 2015, for autumn. A total of 19 survey sites were randomly selected. The weed species were summarized as a total of 63 taxa belonging to 24 families. Specifically, 18 exotic weeds, belonging to 9 families, were identified. The majority of weeds were Compositae (10), followed by Poaceae (7) and Polygonaceae (6). Rumex crispus and Poa annua were dominant weeds. In terms of life cycle, there were 17 species of annual weeds, 13 species of biennial weeds, and 17 species of perennial weeds for the spring survey, and 15 species of annual weeds, 6 species of biennial weeds, and 11 species of perennial weeds for the autumn survey. The continuous application of single control method was unbeneficial for weed management in pear orchards. These results could be useful for the establishment of weed multi–control methods in pear orchards in Chungnam province of Korea
