产地检疫工作浅析

产地检疫,是防止检疫性有害生物传播蔓延的根本途径。近年来,西安市长安区林业种苗生产繁育工作发展速度较快,苗圃总面积273hm＾2,每年的产地检疫率都在95%以上。要做好苗木检疫工作,提高产地检疫率,首先要加强产地检疫的宣传教育力度,增强人们对产地检疫工作重要性的认识,通过培训学习,不断强化检疫员的综合素质,切实有效地做好苗圃地的产地检疫工作。     

内蒙古农牧交错带地名特征浅析——以扎鲁特旗为例

以内蒙古扎鲁特旗为例,对内蒙古农牧交错带地名特征进行分析,发现该地带地名与区域地形地貌、居住民族、土地利用方式及人口迁移等密切相关.具蒙古地名的村屯为原有地名,多分布于牧区和半农半牧区,其地形地貌主要为中山山地、沙丘平原和低山丘陵,居民多为蒙古族.具汉语地名的村屯多为清末形成,主要分布于农业区,其地形地貌为冲洪积平原和...     

行政村地名分布与自然地理要素关系的初探——以毛乌素沙地与黄土高原交界地区为例

地名作为对地表特定地域空间的指称,可以反映特定时期地域的地貌、水文、植被等自然环境特征。以位于毛乌素沙地与黄土高原交界的榆林地区5个市(区)县的1 704个行政村名作为离散点,在ArcGIS中进行核密度分析(Kernel Density)和多距离空间分析函数(Multi-Distance Spatial Cluster Analysis)分析,并对地名蕴含的自然地理要素信息进行了分类统计和特定自然要素地名的缓冲区分析(Buffer)。结果表明:区内行政村的分布总体呈现显著的集聚分布,其中榆阳区和横山区的聚落密度最高。1 704个行政村名与自然要素有关的为1 542个,占85.97%。其中以水文类要素命名的地名最多,占41.73%; 地貌类的地名占31.04%,此外还有与方位、植被、颜色等要素有关的地名。水文类地名的分布可以指示环境变化。部分水文类聚落点与现代河流湖泊距离较远,可能与近两千年来气候总体呈干冷趋势发展,有关风沙活动加强,地表水环境恶化,一些河流流量减少甚至消失有关。     

Spatiality,belonging and citizenship in the age of migration in contemporary China

While internal migration in contemporary China ascribes a great change to urban China's demographic composition, social structures and economic development trajectories, it is yet to restructure the formal definitions of urban identity and belonging, which are still dominated by the household registration system (hukou). The paper suggests that as a result of changes in the political, economic, demographic and social contexts within which China's internal migration develops, there emerge a crucial need to re‐examine the crude forms of determining identity and belonging, questioning the addressing of spatiality within the existing mechanisms (such as hukou system or the shiminhua discourse). To do so, the paper argues that the existing de‐territorialisation of the migration experience has to be replaced with a more nuanced understanding of how spatial practices and conceptualisations shape migrants’ experiences, as it is becoming imperative to develop a new framework that is more sensitive to migrants’ lived process of identification and belonging, especially as these traverse multiple geographies and spatial scales. This close engagement with migrants’ spatiality can then be used as a base from which to engage with a more complex view of migrants’ spatial and social relatedness, as well as the development of their urban belonging and identity.

中国不同地理来源籼稻地方品种的亲缘关系研究

利用61对SSR引物对原产于中国14个省的440份籼稻地方品种进行了SSR分析,并对各省、经度和纬度间的籼稻地方品种进行了遗传距离和聚类分析。结果表明,籼稻地方品种遗传距离变异范围在各省份间为0.0707~0.4076;经度间为0.0680~0.3032;纬度间为0.0385~0.2696。相邻的省份、经度、纬度的籼稻地方品种基本归为同一类群,遗传距离和亲缘关系较近,而地理位置相隔较远的省份、经度、纬度的籼稻地方品种基本归为不同类群,遗传距离和亲缘关系较远,说明籼稻地方品种的亲缘关系与地理位置有着密切的相关性。但按经度和纬度划分较按省份划分的品种间遗传距离更具有规律性。

A model of leisure involvement,residential satisfaction,and place attachment in passive older migrants

Although the influence of mobility on place attachment has received attention in the literature, this relationship varies between groups. Unlike those who move to enjoy their retirement, for example, older migrants arriving in Shenzhen come to the city ‘passively,’ drawn by the needs of their children. This paper advances understanding of the concept of place attachment by illustrating the relationships between its components. Analysis of interview and questionnaire responses revealed the following relationships between three focal components of place attachment. Place dependence first directly influenced affective attachment and then indirectly affected place identity. Leisure involvement had a positive impact on place dependence and affective attachment but no direct effect on place identity. Residential satisfaction was an antecedent of all three focal dimensions of place attachment. No direct relationship was found between leisure involvement and residential satisfaction.
