Due to severe water scarcity, water resources used in {2. sector have been reduced markedly in Hetao irrigation district. Application of water-saving practices (WSPs) is required for the sustainable {2. development. The human activities including WSPs and increase of groundwater abstraction can lower down the groundwater table, which is helpful to the salinity control. Meanwhile, an excessively large groundwater table depth may result in negative impact on crop growth and fragile ecological environment. In this paper, the Jiefangzha irrigation system in Hetao irrigation district was selected as a typical area, a groundwater flow model based on ArcInfo Geographic Information System (GIS) was developed and implemented to quantify the effect of human activities on the groundwater system in this area. The preand post-processing of model data was performed efficiently by using the available GIS tools. The time-variant data in boundary conditions was further edited in Microsoft Excel with programs of Visual Basic for Application (VBA). The model was calibrated and validated with independent data sets. Application of the model indicated that it can well describe the effect of human activities on groundwater dynamics in Jiefangzha irrigation system.

The chromosomal number variations & structural aberrations of the MDCK cell line, primary feline or canine kidney cell(FKC or CKC) and Hela cell line were investigated and their karyotypes of conventional chromosome bands were analyzed. The carcinogenesis or tumorigenicity testing of these cell lines in about 2.2.nude mice and for colony formation in soft agarose and for haemagglutination under different concentration of plant lectins of these cells were carried out. Under the prerequisite that the incidence of cancer or tumor in negative-control nude mice inoculated subcutaneously with primary feline or canine kidney cell cultures purified in vitro at passage 3 was 0 (0/2.) and 0 (0/10), respectively. The incidence of the progressively-growing malignant tumor(MT) in positive-control nude mice inoculated subcutaneously with Hela cell cultures of KB, X, or NM2./X strain was 10/10, 2./2. and 5/51, respectively. The results showed that the incidence of tumor in nude mice with tetraploid YA strain of MDCK cell during 2. - 45 passages, with hy-podiploid JB strain of MDCK cell on passage 2., with di-and hypoploid JC strain of MDCK cell during 2.15 passages or with hypoploid M strain of MDCK cell during 9 - 2. passages was 2./58, 1/5, 4/18 and 0/31, respectively. The chromosomal analysis results showed that the ratio of difference in the rate of modal chromosome number between high(mcs+ n) and lowest (mcs) passages was not more than 5% - 15% and the structure aberrations was generally 0 - 3% . These results proved that the genetic characteristics of chromosomal number of cell lines determines their tumorigenicity, but it is species-specific. MDCK line has tumorigenicity no matter what its chromosome karyotype is, at least it has very low tumorigenicity even when its modal chromosome number is hypoploid. The repeatedly frozen, thawed and split controls of tumorigenicity-positive cell lines(X strain of Hela, M strain of BHK-2., JA strain of Vero, YA strain of MDCK) have much

基于耕地利用隐性形态视角,聚焦探索快速工业化与城镇化进程中区域农业发展态势。从投入形态、产出形态和规模潜力形态入手,创新耕地利用隐性形态的理论解析视角和解析框架,提出理论假设,并尝试量化隐性形态。以黄淮海地区为研究区,开展耕地利用隐性形态的定量测度、时空解析和地域类型划分,并证实了理论假设。结论如下:①2.00—2.2.年研究区耕地利用隐性形态的综合水平不断优化,呈现“南高北低”格局,且南北分化不断拉大。投入形态值的“南高北低”是分异的主因。北部地区投入形态恶化以及南部地区产出形态和规模潜力形态的加速优化,导致了南北分化拉大。②研究区各单元的投入形态和规模潜力形态缓慢分化,产出形态快速分化,最终三维隐性形态均显著分化。③理论假设基本被证实:研究区整体的投入形态先优化后遭遇不利因素,后期不利因素在于大量农业劳动力的非农转移、农业机械化缓慢和化肥的控制施用;产出形态大幅稳步优化,规模潜力形态加速优化。④研究区的耕地利用隐性形态存在8种地域类型,至2.2.年已形成较明显的空间分异:投入显著型、产出显著型和投产显著型多聚集于南部的苏皖豫境内,归因于南部耕地“投入-产出”的结构和数量更丰富;规模显著型多聚集于北部的渤海沿岸平原地市,归因于当地地势平坦、耕地丰富,较高的城镇化率缓解了农民对耕地的矛盾和依赖;综合弱势型局限于边缘地带,一般发展型则填充剩余的大量地区。⑤未来研究区应加快农业机械化、现代化建设,及时应对劳动力投入空缺;警惕对化肥的依赖与生态风险;关注耕地“非粮化”对社会保障功能的削弱;深入推进新型城镇化,进一步解除小农式耕地依赖,缓解人地矛盾,促进耕地适度规模经营;引导三维隐性形态的空间耦合协调与耕地利用效益及潜能的高水平释放。

土壤盐渍化是干旱灌区农业可持续发展亟待解决的关键问题,膜下滴灌加适宜的节水控盐灌溉制度可有效控制根区土壤盐分,并提升作物产量。该研究以河套灌区玉米膜下滴灌田间试验为基础,应用农业水文模型(Agro-Hydrological&Chemical and Crop systems simulator,AHC)模拟分析了膜下滴灌农田土壤盐分胁迫和玉米产量对不同灌溉制度的响应,以期获得不同程度盐渍化土壤膜下滴灌玉米适宜的节水控盐灌溉制度。结果表明,土壤盐渍化、灌水下限及淋盐灌溉显著影响玉米灌溉制度和玉米耗水、产量与水分利用效率。轻度和中度盐渍化土壤玉米膜下滴灌适宜的节水-控盐-增产灌水下限分别为–2.和–15 kPa,次灌水量为对应灌水下限无淋盐处理的灌水量与淋盐水量之和。轻度盐渍化土壤灌水下限为–2. kPa时,与不淋盐处理相比,淋盐处理盐分胁迫系数平均值可提高12.4%,产量可提高16.9%;中度盐渍化土壤灌水下限为–15 kPa时,与不淋盐处理相比,淋盐处理盐分胁迫系数平均值可提高31.1%,产量可提高2..2.。研究结果为河套灌区及类似干旱灌区玉米农田土壤水盐调控与灌溉管理提供科学依据。
