论住宅合作社制度的重新激活——以破解合作住宅“拿地难”为切入点 [PDF]
, 2018 住宅合作社是合作社的一种形态,是有住房需求的中低收入家庭的人合组织,其开发的合作住宅是政府主导供给的社会保障性住房之外的必要补充,具有独特功能和价值。然而由于住宅合作社的发展存在相关立法不周延、与地方政府目标乖离、面临其他用地主体竞争以及缺乏金融支持等障碍,合作住宅越来越难以取得土地,住宅合作社运动陷入低谷、几近停滞。重新认识合作住宅在住宅体系中的定位,完善住宅合作社立法,修正地方政府政绩导向,平衡住宅合作社与其他用地主体关系,加强对合作住宅开发的金融支持,是解决住宅合作社拿地难问题 ...

Shuitu Baochi Xuebao, 2003 选择松嫩平原西部盐碱化程度最高的大安市叉干镇明乐村,研究碱斑地的蒸散过程、土壤水分入渗过程,以及盐分运移和水盐平衡规律,进一步探讨该地区盐渍荒漠化的形成机理。结果表明:碱斑地没有植被覆盖,蒸散过程以土壤蒸发为主,水分运动带动盐分大量向土表积累;碱斑地土壤水分入渗率低,下行盐分远远小于上行盐分。土壤表层盐分累积的结果,使得该地区的草地景观退化,碱斑地面积增加,导致盐渍荒漠化程度加剧。

Shuitu Baochi Xuebao, 2002 应用盆栽试验与大田试验相结合的方法,对从国外引进的3种豆科植物(多年生香豌豆、美丽鹧鸪豆、犹它甜苕子)的抗逆性进行了试验研究。结果表明:美丽鹧鸪豆极耐旱,抗盐碱性能力极强,在盐碱性较大的沟坝地、河滩地,特别是在黄淮海平原的盐碱化土地上均能正常生长,但由于其物候期相当长,在黄土高原地区难以彻底完成其生育期,故从目前情况来看,不宜在该区推广;多年生香豌豆耐旱、耐寒、耐盐碱,抗逆性强,与对照紫花苜蓿相仿,适宜在黄土高原地区推广种植;而犹它甜苕子抗逆性较弱,暂不宜在该区大面积推广 ...
