With the development of social economy and the increasing demand for plowland, the contradiction between tidal flat reclamation and environment protection becomes more and more outstanding. However, tidal flat reclamation should also follow the dynamic balance of total amount of tidal flat amount. The paper analyzed the history of reclamation and development of Jiangsu mud coast, and calculated the feasible rates of tidal flat reclamation on different stretches respectively, and pointed out that both the economic social benefits of reclamation and the natural erosion-accretion conditions of the coasts should be taken into consideration in deciding the intensity of tidal flat reclamation, so as to satisfy demands on both reclamation and protection of tidal flat resource.展开更多

The coastal erosion feature and morphological evolution at the Feiyantan coast are studied in the light of the topography and section depth, and the corresponding dynamics of wave and current. Results indicate that the protruding topography left after the Diaokou River distributary was abandoned is the main cause of strong coastal erosion. Further research suggests that waves start up the sediment and the tidal current transports it, and the waves and tidal current are combined to be the dominant dynamic mechanism of coastal erosion, in which the tidal residual current takes and transports the sediment outward, thus causing the sediment to wane in the coast.展开更多

Remarkable seasonal variations in environmental parameters, and tintinnids composition were observed. Tintinnids samples were enumerated and identified from 5 stations. 14 species belonging to 7 genuses of tintinnids were identified, and the dominate species was Leprotintinnus simple in these season. High tintinnids diversity and low abundance occurred in the fall, and on the contrary, low tintinnids diversity and high abundance occurred in the spring. No significant correlation occurred between tintinnids abundance and nutrients. Tintinnids abundance showed negative relationship with salinity （r2=0.63, P 〈 0.05）, maybe this was due to the cold raised water carried sum nutrients rise to the surface water in the fall, rich nutrients and high phytoplankton biomass decrease the importance of tintinnids in the energy flow of aquatic food web.展开更多

By counting and analyzing the tropical cyclones affecting Guangxi coast from 1950 to 2012, we find that the annual number of tropical cyclones changes significantly, and the maximum value can be up to 9, whereas the minimum value is 0 in some year. The regularity of seasonal distribution of tropical cyclones is obvious, and the peak period is in July, August and September every year, followed by June and October. Most of tropical cyclones come from the east of Philippines. After entering the South China Sea and passing through Hainan province and Leizhou Peninsula, they landed on Guangxi coast once again and caused the mean of peak surge reaching 111.2 cm, which is 2.6 times of non-landing typhoon. The formation of storm surge disaster is directly related to the severe typhoon weather systems, diurnal spring tide and discharge of river flood. Severe typhoons generate huge waves and rainfall, which lead to the rise of water level at the estuary, and would result in significant increasing water when stacking up with the storm surge, and cause huge tidal disaster.展开更多

A soil water balance model was used to assess crop water uptake over two critical growth stages, namely stem elongation and yield formation, to be correlated with cane yields. Under simulated rainfed conditions, average yields performed on yearly basis （from 1991 to 1997） in both sites were highly dependent （linearly） on average crop water satisfaction ratio （ETa/ETm） over these critical growth stages. Under real field conditions in Ferke 2 （irrigation water being considered in addition to rainfall）, cane yields of early as well as late maturing sugarcane varieties obtained on yearly basis were dependent on average crop water satisfaction ratio over both growth stages. In Zudnoula, cane yield fluctuations were generally not predicted by crop water satisfaction ratio, regardless the cropping season considered. However, average cane yields obtained from year to year over the study period in both sugarcane schemes were highly dependent on the average crop water uptake ratio. This shows the important contribution of water in predicting yearly variations of average cane yields produced on Ivorian sugarcane commercial plantations.展开更多

Total fecundity （absolute and relative） were calculated using fish length, weight and eviscerated weight of gonads. Absolute fecundity by size class oscillates from 33,375 to 56,391 eggs with an average of 48,686 ±11,470. The relative fecundity ranges from 34,802 to 139,636 eggs per 100 g body weight with an average of 96,955 ± 33,814 and it is varying between 15,544 and 46,561 per gram of gonad with an average of 28,595 ±20,251. The distribution of oocytes shows that stages I and II are presented throughout the spawning season and they constitute a stockpile for subsequent clutches.展开更多

It occupies a 2.5 km long of coastline on the Atlantic shore. It is oriented NNE-SSW, clearly exposed to the dominant swells coming from west to northwest. The aim of this study is to determine the capacity of the waves that hit the shore to transport the sediments. To achieve our goal we chose a methodology that combines field sampling and laboratory analysis with digital modeling. In the first phase we sampled sediments from the study area along and across the beach line, dry sieving was used to determine the grain size distribution and the statistics derived from the sand samples were used to determine the critical shield stress （z＇cr, b） also to investigate the spatial variability and influence of transport on grain size characteristics. As for the second phase, we intended to create a wave climate modeling based on nautical chart, using ArcGIS then Matlab that allowed us to obtain the Swan model for the area. The correlation between those results showed the degree of contribution of wave in the distribution of sediments along the shore.展开更多

文摘The influence of water deficit as main cane yield limiting factor in Ivory Coast was investigated on SUCAF Ferke 2 and Sucrivoire Zuenoula sugarcane commercial plantations. A soil water balance model was used to assess crop water uptake over two critical growth stages, namely stem elongation and yield formation, to be correlated with cane yields. Under simulated rainfed conditions, average yields performed on yearly basis （from 1991 to 1997） in both sites were highly dependent （linearly） on average crop water satisfaction ratio （ETa/ETm） over these critical growth stages. Under real field conditions in Ferke 2 （irrigation water being considered in addition to rainfall）, cane yields of early as well as late maturing sugarcane varieties obtained on yearly basis were dependent on average crop water satisfaction ratio over both growth stages. In Zudnoula, cane yield fluctuations were generally not predicted by crop water satisfaction ratio, regardless the cropping season considered. However, average cane yields obtained from year to year over the study period in both sugarcane schemes were highly dependent on the average crop water uptake ratio. This shows the important contribution of water in predicting yearly variations of average cane yields produced on Ivorian sugarcane commercial plantations.
文摘In the present paper, a study of the productivity of oocytes in 402 female individuals of the horse mackerel, Trachurus trachurus for an interval of fork length （LF） between 14 cm and 20 cm, in stage IV （pre-spawning） and V （spawning） was performed to estimate the fecundity rate in Oran Bay （Algerian western coast） since October 2008 to April 2009.
