Shuitu Baochi Xuebao, 2007 土壤中的水分是影响半干旱区作物生长的重要因素,由于自身的特点决定了其在空间分布上存在着变异性。以黑龙江省西部半干旱农业气候区的查哈阳农场为研究对象,利用GS 地统计软件和ArcGIS中的地统计分析模块(Geostatistical Analyst),对该地区土壤水分特性的空间变异性进行分析,得出土壤水分特性的变异程度、影响因素以及空间分布图。借助于土壤水分特性的空间分布图对该地区的灌溉水量进行了分析,为该地区的合理灌溉和精确灌溉提供依据。

Research on Urban Life Circle System and Its Optimization Based on Multi-Source Trip Data: A Case Study of Xiamen City [PDF]
, 2016 城市的发展、科技的进步，触发了人们生活观念和生活方式的转变，使得研究者对重塑便捷、安全、合理的生活空间的探索热情愈加高涨。当前，城市规划面临由“生产空间导向”向“生活空间导向”的转型，关注城市居民日常生活，研究城市形态表象下的居民行为规律已然成为了城市规划研究领域的热点问题。本论文在分析城市生活空间组织方式转型必要性的基础上，通过对国内外已有生活圈理论进行总结探讨，从城市出行活动层面探讨生活圈体系的构建问题，提出以出行活动为原点、以复杂网络及社团发现为理论基础的城市生活圈构建及优化方法 ...

An Empirical Study on Urban Residential Differentiation ——Take Jinxiang Community of Wucun Street in Xiamen for Example [PDF]
, 2009 我国城市居住空间分异现象是伴随着80年代的市场经济体制改革及90年代开始的住房商品化进程逐渐衍生出来的。针对北京、上海、广州等大城市的研究表明，我国城市居住空间分异现象已在多种尺度上出现。本研究以梧村街道金祥社区为例，考察现阶段厦门市的居住空间分异及其分异的程度。对厦门的研究将有助于了解类似于厦门的我国其他中小城市居住空间分异现象的发展状况，从而更好、更全面地把握我国城市居住空间分异现象的总体进程。 本研究在划分不同类型住宅区的基础上，对不同类型住宅区居民的收入、职业、文化程度 ...

Synthesizing Empirical Research on Learner Metacognition in Second Language Writing
International Journal of Applied Linguistics, EarlyView.ABSTRACT Despite considerable research interest in learner metacognition in second language (L2) writing, there is not yet a review that synthesizes the existing empirical findings and discusses their implications. To fill the void, this systematic review synthesized 39 empirical studies on learner metacognition in L2 writing and examined their salient

Shuitu Baochi Xuebao, 2004 利用地统计学对黑龙江省双城市薄层农田黑土的全碳和速效氮、磷、钾的空间异质性进行了分析,结果表明四者均具有空间异质性。土壤全碳含量的空间异质性最高,主要受黑土层厚度的影响,土壤速效氮磷钾的空间异质性较差,主要受随机因子的影响,占80%以上。全碳和速效氮、磷、钾的空间有效最大相关距离分别为15.7km,4.6km,11.2km,7.1km。土壤全碳与碱解氮存在极显著正相关。

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT With the growing severity of volatile organic compounds (VOCs) pollution, metal‐organic frameworks (MOFs)‐derived materials offer a promising solution through efficient photothermal catalysis. In this paper, M‐MnOx (M = Cu, Ni, Co, Fe) catalysts derived from manganese‐based MOFs were successfully prepared by the sacrificial template method and
