Quantification of Terrain Variation in Mountainous Regions based upon Numerical Map Analysis by means of Electronic Computer (III) : Accessibility to the Modelling of Terrain Configuration employing the Minimum AIC Estimation (MAICE) procedure [PDF]
, 1983 計量モデルが離散的な有限個のデータから構造と誤差とを分離する過程を通して構成されると考えるならば (統計的誤差処理), これには 〔1〕 データ特性に関するアプリオリな知識に基づいてモデルが的確に構成されること, 〔2〕 想定されるモデルの中から適切なモデルを比較・評価するための客観的基準が提示されること, 〔3〕 得られたモデルによって何らかの予知・予測が可能になること, が不可欠な条件となる。これらのいずれかの条件が不備であれば, そのモデルの有効性は損われる。著者等は ...

Policy Studies Journal, EarlyView.ABSTRACT Despite extensive research on policy diffusion, the ways in which policy attention influences this process remain underexplored. This study addressed this gap by distinguishing between three types of policy attention—political speeches, policy issuance and field visits—and investigating their differential impacts when delivered by central and ...

DEM在旱耕地荒漠化评价中的应用——以武威,古浪二市（县）为例
Shuitu Baochi Xuebao, 2000 荒漠化在干旱地区最为普遍，旱耕地的存在加速了荒漠化发展。ＤＥＭ是通过计算机系统产生的数字高程模型，进行地形分析，模拟地貌形态，直观显示地貌特征和地形部位。在ＥＳＲＩ地理信息系统的支持下，通过数字化地形等高级图，产生数字高程模型（ＤＥＭ），并通过ＤＥＭ，计算派生出坡度图，以其作为基本图件，结合土地利用图和相关资料，用地理信息系统进行综合分析，提取旱耕地的信息。

Policy Studies Journal, EarlyView.ABSTRACT Based on the Punctuated Equilibrium Theory (PET) and implementation research, this study proposes an extended conceptualization of policy punctuation that enables researchers to systematically include policy implementation as part of a punctuation. The key mechanisms underlying the PET, i.e., policy image and venue, information processing, and

Shuitu Baochi Xuebao, 2023 探究不同人为管理措施坡耕地地表微地形变化特征,阐明地表微地形变化对渗流响应,以期为紫色土坡耕地水土流失的有效防治与人为管理措施的合理布设提供科学依据。以平整坡面、穴播坡面和垄作坡面为研究对象,基于室内人工模拟渗流试验,开展5°和15°紫色土坡面微地形变化特征研究。结果表明:(1)渗流试验前后平整坡面、垄作坡面和穴播坡面微地形半方差函数在0~135°和180°~315°方向上呈中心对称分布,随地表坡度的增加分布范围逐渐缩小,且具有明显的方向性。渗流条件下,平整坡面和穴播坡面微地形各向异性的变化趋势较为一致,

Emotion and the Advocacy Coalition Framework: An Affective Dynamics Perspective
Policy Studies Journal, EarlyView.ABSTRACT Despite extensive evidence that emotion and cognition are deeply intertwined, the Advocacy Coalition Framework (ACF) lacks an analytically independent emotional mechanism in its causal architecture—an omission that may be particularly consequential in policy subsystems structured around morally charged, identity‐laden policy disputes.

Shuitu Baochi Xuebao, 2005 首先论述了以地理信息系统(GIS)为平台，基于分形信息维数(FID)表征地貌形态特征的原理和方法．采用Avenue语言开发了基于ArcGIS环境下地貌形态特征FID计算软件；并以长江流域白水溪小流域为例，进行了不同等高距下地貌形态特征FID的计算，通过对FID与等高距耦合关系的深人分析，结果表明：基于FID不仅可以对流域地貌形态特征进行宏观性、综合性定量表征，而且能够实现不同等高距下流域地貌形态特征的相互转换，有利于与流域形态特征相关联的水文、水土流失过程的动态模拟．同时可实现对现有地形数据的充分挖掘 ...
