    随着近几年中国经济形势向好,中小企业的数量快速增长,担保公司的数量也有了迅猛的增长。厦门的担保业正在进入战国时期,在未来几年的时间里各家担保公司将面临行业整合、优胜劣汰的局面。本文主要从竞争战略方面来探讨福建省XX担保投资有限公司(以下简称XX担保公司)在未来发展中应该采取的战略。作者结合XX担保公司成立以来的发展历程,首先总结了XX担保公司在发展中的宝贵经验,接着从厦门市担保行业现状、行业发展趋势等方面对该行业进行了深入分析,以探讨厦门市担保行业的发展前景及XX担保公司继续在该行业经营应该采取的最佳策略。其次,本文给出了厦门市担保行业的成功关键因素,分析了XX担保公司在这几个因素上的能力,并...With the development of China’s economic, the amount of the medium and smallsize enterprises grows very fast. All the companies face serious competition, thecompany will be washed out if can’t adjust in time. So in this thesis, I’d like to discuss what kind of strategy XX Guarantee should choose. Firstly, in order to find out the best strategy for XX Guarantee Company, I reviewed the development p...学位:工商管理硕士院系专业:管理学院工商管理教育中心(MBA中心)_工商管理硕士(MBA)学号:20021502

    吉林省东部山区獐潜在适宜分布及生态廊道构建

    基于在吉林省东部山区野外调查获得的96份獐(Hydropotes inermis)的位点数据及16份环境变量数据,利用MaxEnt模型和Linkage Mapper工具识别獐潜在适宜分布区及连通性,构建生态廊道,为今后开展相关研究提供基础数据及现实指导。结果表明:MaxEnt模型预测精度较高,AUC值高达0.9以上,在当前气候条件下,獐主要分布于珲春市、敦化市、白山市和集安市等海拔偏低且坡度平缓的部分地区,植被类型多为草本覆盖层。对獐潜在适宜分布区影响较大的环境因子包括植被类型-草本覆盖层、海拔、植被类型-灌溉农田、人为干扰和坡度等。以MaxEnt模型分析的獐适宜区分布情况为研究基础,构建的9条生态廊道多为水源丰富,且远离人群居住的区域。生态廊道是实行生境适宜性恢复的相关措施,廊道对保护生物多样性和调节生态系统平衡具有关键作用,相关部门可依据其重要性,为实施物种保护计划提供参考

    The cysteine protease gene MdCP2 plays an important role in responding to drought stress. In this study, the experimental materials were one-year-old M9T337' apple seedlings subjected to natural drought treatment. We determined the photosynthetic characteristics, plant water content, differentially expressed genes and the function of cysteine protease gene MdCP2 in leaves of apple seedlings during natural drought and rehydration process at physiological and molecular biological levels. The results showed that the photosynthetic rate, stomatal conductance and transpiration rate decreased under drought stress. In the later stage of natural drought, the major limiting factors of photosynthesis changed from stomatal restriction to non-stomatal restriction. The qRT-PCR results showed that MdCP2 had the higher expression level in roots and its expression had a significant positive correlation with the the degree of drought. The expression levels of MdRCA, MdCAB and MdRBCS were negative correlation with the degree of drought. Yeast two-hybrid and BiFC techniques were further used to demonstrate that MdCP2 interacts with MdGLK1. These results provide a theoretical basis for further study of cysteine protease MdCP2 gene

    黑龙江老爷岭东北虎国家级自然保护区土地利用与景观格局变化研究

    土地利用和景观格局变化研究是自然保护区制定管理和保护规划的重要依据。本研究以黑龙江老爷岭东北虎国家级自然保护区1999—2019年3期的土地利用数据为基础,利用动态度与转移矩阵模型对该区的土地利用变化进行分析;选择斑块数量和香农多样性等景观指数对其景观格局变化进行研究。结果表明,林地是老爷岭保护区主要的土地利用类型,约占自然保护区总面积的95%,且1999—2019年呈稳定趋势(K=-0017)。从景观格局变化来看,老爷岭保护区的景观呈破碎化趋势,其中斑块数量和香农多样性指数变化最大。从时间跨度来看,1999—2009年是老爷岭保护区土地利用和景观格局变化的主要时段,自2009年后老爷岭保护区建立,保护区内的土地利用动态度指数和景观破碎化程度均在降低,这说明老爷岭保护区成立后,随着管理和保护力度的加大,保护区内的林地得到了一定程度的恢复,景观破碎化程度得到了有效改善
