No escape from the dominant theories: The analysis of intellectual pillars of technology management in developing countries

This paper aims to identify the intellectual bases of the technology management (TM) literature generated in developing countries using citation and co-citation analyses and answer the question of whether the intellectual bases of the TM literature created by authors in developing countries diverge from those of the global TM literature. Based on a comprehensive bibliometric analysis of ten technology-innovation management (TIM) specialty journals through the period of 1998-2007, this study produces three important findings. First, the TM literature generated in developing countries is dominated by the knowledge and theories created in developed countries. Second, among these knowledge sources some authors from developing countries and focusing on the specialties of developing countries, such as Kim and Lall, come into prominence; however these authors are not even mentioned in the previous bibliometric studies covering overall TM research. Finally the researchers in developing countries tackle with the issues or topics specific to their own context through combining three major bulks of literature. These are (i) resource-based view (RBV)/core competencies and organizational learning related research; (ii) literature dealing with the evolutionary theorizing on economic change and growth and (iii) literature related to technological capabilities, technology transfer and industrialization in developing countries.     

高海拔地区TM遥感数据信息的提取与DEM获取研究

本研究以Landsat TM遥感数据为研究对象,以杂谷脑河流域为例,从遥感数据的几何校正、最佳波段选择、图像融合、图像裁剪、土地分类和图像的解译角度进行了处理.之后,将校正后的数据进行了矢量化并得到DEM,在DEM的基础上进行了高程、坡度、坡向方面的分析,得到了有利于LUCC分析的可靠数据.     

基于TM与ASAR数据的矿区塌陷地信息提取

研究目的：实现多光谱数据与雷达数据的综合应用对矿区塌陷地信息的提取,评价多源遥感数据在塌陷地信息提取中的精度与优势。研究方法：主成分分析融合法、波段运算法、密度分割法等。研究结果：以ENVISAT-ASAR和TM影像数据为数据源进行研究,结果显示该方法不仅对水体本身有较好的提取精度,而且对塌陷区深浅、非积水区、塌陷区不规则边缘、植被覆盖情况等信息有非常好的提取效果,塌陷地提取精度较高。研究结论： TM数据光谱特性和ASAR波段数据微波特性的综合应用对塌陷地积水区提取有较高的精度,能够为塌陷地研究提供技术支持。     

2000-2010年海淀区自然地理要素时空分布动态监测研究

近年来,我国经济飞速发展,自然地理要素不断变化,而遥感技术以其多空间、时间和光谱分辨率的特征已成为调查自然地理要素的主要手段。本文以北京市海淀区为例,基于2000年和2010年的TM影像,采用监督分类和分类后处理的方法对海淀区10年间的自然地理要素变化情况进行了研究分析。

The impact of exurban development on forested areas in Kurgan City,Russia

Exurban communities—a significant form of urban sprawl—can transform natural land cover. Exurban development refers to an expansion of communities located outside a city and its suburbs. One of the main reasons these settlements develop is a desire by residents to live closer to nature and developers’ recognition of the profitability of addressing this desire. Additionally, exurbs can become prosperous regions settled by people with high income. However, exurban development not only directly affects community patterns, but also species patterns, habitat reduction and disconnection, as well as land cover and land use alterations. The purpose of this paper is a quantitative analysis of the land cover transformation and forest fragmentation in Post-Soviet Russia, based on an empirical case study of the city of Kurgan. This case study also contributes to the overall research of urban sprawl in Russian provinces by adding to the discussion of homeowners’ behavior, regional environmental policies, and their role concerning the impacts of exurban settlements on the natural environment. This paper uses remote sensing imagery, census data, and primary data to analyze land cover change due to the emergence of exurban communities around Kurgan, Russia, with specific emphasis on the changes to native vegetation resulting from human behavior and stakeholder preferences.

基于ENVI的TM影像变化信息检测方法与实践——大连市部分海岸带变化信息检测

变化信息检测是目前遥感应用领域的研究热点,目前尚未发现一种通用的变化检测方法。见诸文献中众多的变化检测方法,其实质可以分为两种类型,即光谱直接比较法和分类后比较法。在ENVI环境下,采用光谱直接比较法和分类后比较法对大连市普兰店湾及普兰店湾渤海入海口地区的TM影像进行试验。结果表明:边缘检测方法、水体信息提取法对于快速发现变化区域是有效的,而分类后比较法在提供详细的变化信息上具有明显的优势。     

基于遥感的阿鲁科尔沁旗人工饲草面积及生产经济变化分析

目的 人工饲草的种植规模和生产水平是衡量一个国家畜牧业发达程度的重要标志。及时准确地获取人工饲草种植面积,分析人工饲草生产的长期变化趋势,为饲草产业的发展和管理提供科学的数据支撑。方法 文章以内蒙古自治区赤峰市阿鲁科尔沁旗为例,基于Google Earth Engine（GEE）云平台和Landsat卫星遥感数据,依据玉米、苜蓿、燕麦3种饲草作物的生长特性和物候差异,使用机器学习算法对2000—2020年3种饲草作物的种植面积进行了逐年提取。在此基础上,结合入户调查数据,分析了3种人工饲草的种植面积、产量、价格在2015—2020年的变化趋势。结果 2000—2020年3种饲草作物的种植面积均显著增加,增加的区域位于研究区西部、南部的退化草地和沙地,以及河谷等水资源丰富的区域。在3种人工饲草中,苜蓿种植发展最为迅速,在2010年后种植面积和产量均快速增长;燕麦的种植起步较晚并且种植面积最小;青贮玉米的产量虽然在稳步增加,但是青贮玉米种植面积占全旗玉米总种植面积的比例并没有增加。结论 阿鲁科尔沁旗人工饲草的种植在2010年开始快速发展,在2015年形成规模化种植,进入平稳发展阶段。人工饲草的种植能够改良退化草地和沙地,但是受水资源分布的影响。苜蓿和燕麦的产量增长是因为种植面积的扩大,青贮玉米产量的增长是因为单产的增长。人工饲草的种植虽然快速增加,但是饲草缺口仍然不能得到满足。
