城市建设用地规模预测模型探讨——以河北省邢台市为例

国内众多专家学者对确定城市合理用地规模的方法上进行了多角度探索,本研究有益借鉴这些成果,采用多元线性回归分析和BP神经网络2种较成熟的预测模型,选取城市建设用地面积、地区生产总值、固定资产投资、城市人口数、年末道路面积、城市园林绿地面积、商品房平均售价为观测指标,分析预测河北省邢台市的建设用地规模。结果表明,预测结果并不理想,预测值与实际值的误差始终存在,并随时间推移不断扩大,深入分析预测结果产生偏差的原因,即忽视了非理性因素对城市建设用地规模的影响。建议引入行为金融学理论,将研究对象具化到个人,研究土地市场管理者和投资者在决策过程中的认知、行为偏差,分析城市建设用地面积持续蔓延的非理性动力,应用行为组合理论和资产定价模型对传统研究范式进行有益补充和修正,进而更科学地把握城市用地空间形成机制及演变规律。

山西省闻喜县冬小麦水肥管理现状分析

为了解近年来山西省冬小麦生产现状,对山西冬小麦水肥管理进行科学指导,2011—2014连续3年在山西小麦种植面积第一大县闻喜县调查冬小麦水肥管理状况。结果表明,闻喜县冬小麦产量随年际间降水量波动变化较大。由施肥情况分析可看出,水地冬小麦农户平均施氮(基肥+追肥)324 kg/hm~2,72%农户氮肥投入很高,平均施磷(基肥+追肥)141 kg/hm~2,18%农户未施磷肥,49%农户施磷很高,最终氮、磷平均偏生产力分别为16.83 kg/kg、49.63 kg/kg。旱地冬小麦农户平均施氮(全部基肥)152 kg/hm~2,59%农户氮肥投入偏低,平均施磷(全部基肥)120 kg/hm~2,54%农户施磷适中,13%农户施磷很高,最终氮、磷平均偏生产力分别为15.71 kg/kg、23.29 kg/kg。由灌水情况分析可看出,平均灌水次数增加,水地冬小麦产量呈增加趋势。由投入产出分析可看出,水地冬小麦施肥、灌水分别占总投入金额比例为:27%、32%,纯收入为:4285元/hm~2;旱地冬小麦施肥占总投入金额比例为:39%,纯收入为:1150元/hm~2。总之,产量和收入主要因年际间降水量差异较大而不稳,磷肥重视程度提高,但氮肥投入不合理,水地过高、旱地过低,制约产量提高;水地冬小麦施肥和灌水投入、旱地冬小麦施肥投入占总投入比例均较高,对农户收入也有较大影响。     

Campus Design Strategies Based on Spatial Images: A Case Study of Four New Campuses in Chengdu

From 1999, with the rapid expansion of enrollment scale, colleges have experienced fast development and construction of new campuses. However, the urgency of the demand for campus space at that time led to the shortcomings of paying more attention to speed than connotation during the construction of the new campus. Even now the evaluation of new campuses which have been used for nearly twenty years and whether the space of new campuses has played its due role will affect the display of the heritage and temperament of colleges. This paper uses the typical spatial cognitive concept—spatial image to analyse the elements of spatial images on campuses, summarizes the perceptions of teachers and students towards the space of four new campuses in Chengdu through questionnaire survey and analysis, puts forward the principles of campus space design and the strategies of classification design, and intends to take spatial images as the research cut-in point to provide new ideas and suggestions for the design and improvement of campus space from the perspective of users.
