选择祁连山自然保护区4处典型砂石料场植被恢复地为研究对象,研究其植被恢复技术和林下草本植被的物种多样性。结果表明:砂石料场植被恢复技术主要是采坑回填、废弃渣堆平整、河道清淤、废弃建筑物拆除、排导堤修筑、围栏封育、覆土、种植单一的乔木或灌木以及草本植物种。林下植物以冷地早熟禾(Poa crymophila)和垂穗披碱草(Elymus nutans)占据优势地位,其他植物种处于劣势地位。林下植被Margalef物种丰富度指数、Simpson多样性指数、Shannon-Wiener多样性指数和Pielous均匀度指数均偏小,植物多样性维持在较低水平。建议继续加强祁连山自然保护区砂石料场植被恢复区的经营和管理。

本研究旨在探讨不同甜高粱品系在受到干旱胁迫时生理生态响应机制,并筛选出具有优良抗旱性的甜高粱恢复系。实验设计了4个不同浓度的PEG-6000水溶液:50、100、150、200 g/L,并以清水处理作为对照组,通过测量各处理组的发芽率、发芽势、胚芽长、胚根长、芽干重、根干重、干物质转运率等指标,评估了不同甜高粱品系的抗旱性能。研究结果显示,随着PEG浓度的增加发芽率、发芽势、胚根长、胚芽长、芽干重、根干重、干物质运转率整体均呈下降趋势,不同处理下品种2和品种7发芽势表现最好,浓度小于200 g/L处理下发芽势均未出现显著下降,在浓度达到200 g/L分别较对照下降11.5%、17.8%;品种7发芽率表现最好,20%的PEG浓度处理下较对照下降最少(5.6%);品种6胚根长表现最好,150 g/L处理下,胚根长较对照增长7.1%;品种3和品种4胚芽长表现最好,在100 g/L和150 g/L处理下胚芽长均是较对照降低最少。品种2干物质运转率表现最好,所有处理均较对照下降最少。可见不同甜高粱品系应对干旱胁迫的响应机制各有不同。综合分析表明,不同的甜高粱品系对干旱胁迫的适应机制存在差异。通过隶属函数进行综合评价,得出8个甜高粱品系的抗旱性排序为:品种3>品种7>品种4>品种6>品种2>品种5>品种8>品种1。这一结果为甜高粱的抗旱育种提供了重要的理论依据。

Research in Cold and Arid Regions 2016年第2期8卷 116-124页

Soil moisture simulation and prediction in semi-arid regions are important for agricultural production, soil conservation and climate change. However, considerable heterogeneity in the spatial distribution of soil moisture, and poor ability of distributed hydrological models to estimate it, severely impact the use of soil moisture models in research and practical applications. In this study, a newly-developed technique of coupled (WA-ANN) wavelet analysis (WA) and artificial neural network (ANN) was applied for a multi-layer soil moisture simulation in the Pailugou catchment of the Qilian Mountains, Gansu Province, China. Datasets included seven meteorological factors: air and land surface temperatures, relative humidity, global radiation, atmospheric pressure, wind speed, precipitation, and soil water content at 20, 40, 60, 80, 120 and 160 cm. To investigate the effectiveness of WA-ANN, ANN was applied by itself to conduct a comparison. Three main findings of this study were: (1) ANN and WA-ANN provided a statistically reliable and robust prediction of soil moisture in both the root zone and deepest soil layer studied (NSE >0.85, NSE means Nash-Sutcliffe Efficiency coefficient); (2) when input meteorological factors were transformed using maximum signal to noise ratio (SNR) and one-dimensional auto de-noising algorithm (heursure) in WA, the coupling technique improved the performance of ANN especially for soil moisture at 160 cm depth; (3) the results of multi-layer soil moisture prediction indicated that there may be different sources of water at different soil layers, and this can be used as an indicator of the maximum impact depth of meteorological factors on the soil water content at this study site. We conclude that our results show that appropriate simulation methodology can provide optimal simulation with a minimum distortion of the raw-time series; the new method used here is applicable to soil sciences and management applications.

Spatial heterogeneity is an inherent characteristic of natural forest landscapes, therefore estimation of structural variability, including the collection and analyzing of field measurements, is a growing challenge for monitoring wildlife habitat di- versity and ecosystem sustainability. In this study, we investigated the combined influence of plot shape and size on the accuracy of assessment of conventional and rare structural features in two young-growth spruce-dominated forests in northwestern China. We used a series of inventory schemes and analytical approaches. Our data showed that options for sampling protocols, especially the selection of plot size considered in structural attributes measurement, dramatically af- fect the minimum number of plots required to meet a certain accuracy criteria. The degree of influence of plot shape is related to survey objectives; thus, effects of plot shape differ for evaluations of the ＂mean＂ or ＂representative＂ stand structural conditions from that for the range of habitat （in extreme values）. Results of Monte Carlo simulations suggested that plot sizes 〈0.1 ha could be the most efficient way to sample for conventional characteristics （features with relative constancy within a site, such as stem density）. Also, 0.25 ha or even larger plots may have a greater likelihood of capturing rare structural attributes （features possessing high randomness and spatial heterogeneity, such as volume of coarse woody debris） in our forest type. These findings have important implications for advisable sampling protocol （plot size and shape） to adequately capture information on forest habitat structure and diversity; such efforts must be based on a clear definition of which types are structural attributes to measure.

针对高深宽比柔性微米纤维阵列的制造难点,提出了一种利用氟树脂降低纤维表面能结合超声波辅助的方法,以实现高深宽比柔性微米纤维阵列的大面积和低成本制造。利用数学模型研究了纤维贴地倾倒和侧向倾倒的发生条件,在不稳定的情况下,相比于侧向倾倒,高深宽比柔性纤维更易于贴地倾倒,并结合稳定性分析结果进行了相关实验验证。结果表明:通过具有更低表面能的氟树脂对已成型的高深宽比柔性纤维进行表面处理,可有效降低纤维表面能;对于倾倒的高深宽比纤维进行氟树脂表面处理,并辅之以超声振动,能够使得倾倒的纤维恢复到直立状态,当纤维直径为10μm时,其临界稳定深宽比为15.91,提高了纤维的稳定性,实现了直径为10μm、深宽比为10的柔性微米纤维阵列的制造,且制造出的高深宽比柔性纤维具有高度稳定性。
