粮食安全关乎国运民生。当前,我国农村乱占耕地建房问题突出,对粮食安全造成一定威胁,国务院及其相关部门虽多次加大对农村乱占耕地建房的执法力度,但执法效果仍存在较大提升空间。文章通过对筛选的400个农村乱占耕地建房典型案例进行实证分析,认为当前农村乱占耕地建房执法仍存在执法权横向划分不明确、基层执法权纵向配置不合理、综合执法力度不足、执法队伍业务水平不高等问题,并提出明确划分执法权限、推进部门综合执法、下放行政执法权、提高执法队伍业务水平是突破农村乱占耕地建房执法困境、守牢耕地红线、夯实粮食安全根基的因应之策。

宅基地使用权依托农房转让的制度沿革、司法裁判与实践创新

宅基地使用权依托农房转让的制度沿革经历了从允许到限制的转变,体现了政府政策的强制驱动和利益诱导的结合。宅基地使用权依托农房转让的司法裁判具有明显的被动性,农户在集体经济组织外部转让农房时,法院一般会认定该转让合同无效,但司法政策又为宅基地改革预留了政策空间,体现了原则性与灵活性的统一。在宅基地使用权依托农房转让的实践创新中,国家并没有直接废除宅基地使用权依托农房限制转让的既有路径,径行允许转让,而是秉持审慎原则,独辟蹊径。试点地区宅基地使用权依托农房转让下受让人范围拓展,与集体经营性建设用地入市衔接,与宅基地资格权退出耦合及与宅基地入股、合作打通,均体现了对宅基地使用权权能受限的克服。

严寒地区农村住宅围护结构现状分析与优化研究

我国严寒地区气候寒冷且供暖季漫长,农村住宅采暖能耗问题突出,多数住宅采用自建形式,围护结构的热工性能普遍不理想。本研究从严寒地区农村住宅围护结构实际情况出发,对本溪农村地区200余户现有住宅进行调研。结果显示,本溪现有农宅基本未设置外墙保温,虽部分住宅屋顶设置保温,但保温材料均已超过使用年限,保温效果较差。有86.95%的农宅室内温度基本维持在18℃以下,农户满意度仅24.2%。实地测量3户典型农宅的室内环境温度。采用EnergyPlus模拟得到农宅围护结构的传热系数相比居住建筑节能设计标准规定限值超出300%~400%。根据实测数据和模拟数据对外墙、屋顶、外窗进行热工性能改造。对比单一围护结构改造前后的供暖季热负荷,得出外墙的改造效果最好。
