Abstract: ?采用响应面法优化鲜切牛蒡护色保脆复配物l-半胱氨酸、抗坏血酸钙和乳酸钙质量浓度,研究该复配物对牛蒡贮藏期间品质和酶促褐变的影响。结果表明:护色保脆复配物中l-半胱氨酸、抗坏血酸钙和乳酸钙质量浓度分别为0.29、1.2g/100ml和0.2g/100ml时,鲜切牛蒡护色保脆效果最好,鲜切牛蒡经此复配物浸泡30min后,多酚氧化酶和过氧化物酶活力下降,同时苯丙氨酸解氨酶在贮藏前期被激活,第10天的活力为对照的1.5倍。复配物处理后,丙二醛含量低于对照,而总酚含量高于对照。贮藏前期的5d内,复配物处理能较好地保持鲜切牛蒡的颜色和脆性。

Abstract: The sediments of the Dongting Lake come from four channels (one of them was closed in 1959), connected with the Yangtze River, four tributaries (Lishui, Yuanjiang, Zishui and Xiangjiang) and local area, and some of them are transported into the Yangtze River in Chenglingji, which is located at the exit of the Dongting Lake, some of them deposit into drainage system in the lake region and the rest deposit into the lake. The annual mean sediment is 166,555x104 t, of which 80% come from the four channels, 18% from the four tributaries and 2% from local area, whereas 26% of the total sediments are transported into the Yangtze River and 74% deposited into the lake and the lake drainage system. Based on topographic maps of 1974, 1988 and 1998, and the spatial analysis method with geographic information system (GIS), changes in sediment deposition and erosion are studied in this paper. By overlay analysis of 1974 and 1988, 1988 and 1998, erosion and sediments deposition areas are defined. The main conclusions are: (1) sediment rate in the lake is larger than erosion rate from 1974 to 1998. The mean deposition in the lake is 0.43 m; (2) annual sediment deposition is the same between 1974-1988 and 1988-1998, but the annual volume of deposition and erosion of 1988-1998 is bigger than that in 1974-1988; (3) before the completion of the Three Gorges Reservoir, there will be 7.82x108 m3 of sediments deposited in the lake, which would make the lake silted up by 0.33 m; (4) in the lake, the deposition area is found in the north of the east Dongting Lake, the south-west of the south Dongting Lake, and the east of the west Dongting Lake; while the eroded area is in the south of the east Dongting Lake, the middle of the south Dongting Lake, the west of the west Dongting Lake, as well as Xiangjiang and Lishui river flood channels.

Abstract: With the long-term data of the geodetic sea level measurements undertaken in the Dongting Basin and the recent sediment data of Dongting Lake, we analyze the tectonic subsidence rate of the Dongting Basin and the sedimentary rate of Dongting Lake. From the point of view of geomorphology and hydrogeology, we distinguish the two different spatial concepts between "the basin of Dongting Lake" and "the Dongting Basin". Then, we discuss the influences of the tectonic subsidence and the siltation on the space of storing flood of Dongting Lake and the levees. Under the circumstance of the basin of Dongting Lake encircled by levees, the capacity of storing flood of Dongting Lake will decrease due to the tectonic subsidence. The tectonic subsidence capacity of the Dongting Basin restrains the shrinking tendency of Dongting Lake to a certain extent, but the tectonic subsidence is harmful to the situation of preventing flood disasters in the region of Dongting Lake. The better quality of levees is required due to the tectonic subsidence and the siltation, and the difficulties of preventing flood disasters are increasing in the region of Dongting Lake.

The influences of the tectonic subsidence and the siltation on the situation of preventing flood disasters in the Dongting Lake area

Abstract: With the long-term data of the geodetic sea level measurements undertaken in the Dongting Basin and the recent sediment data of Dongting Lake, we analyze the tectonic subsidence rate of the Dongting Basin and the sedimentary rate of Dongting Lake. From the point of view of geomorphology and hydrogeology, we distinguish the two different spatial concepts between "the basin of Dongting Lake" and "the Dongting Basin". Then, we discuss the influences of the tectonic subsidence and the siltation on the levees and the space of storing flood. The better quality of levees is required due to the tectonic subsidence and the siltation, and the difficulties of preventing flood disasters are increasing. The space of storing flood is not affected by the tectonic subsidence, but by the siltation. At present, the sedimentary rate of Dongting Lake is higher than the tectonic subsidence rate of the Dongting Basin. The tectonic subsidence capacity of the Dongting Basin counteracts a part of sedimentary capacity, and the shrinking tendency of Dongting Lake is restrained to a certain extent, but the tectonic subsidence is harmful to the situation of preventing flood disasters in the Dongting Lake area.
