中国房产税制改革略论——从修订《房产税暂行条例》的角度

在物业税短期内难以走完立法程序的前提下,必须通过修改《房产税暂行条例》,将房产税征收对象扩大至个人非营业性用房、农村非住宅用房,并以超过家庭人均住房面积部分作为税基;取消房屋租金收入的计税依据,预防合理避税;以房屋市场评估价格代替房屋原值;因地制宜,实施幅度比例税率,从而达到增加房产保有环节税收,合理引导房地产市场健康发展和理性消费之目的。

农作物秸秆综合利用和禁烧管理国家法规综述与立法建议

[目的]梳理秸秆综合利用和禁烧管理方面的法律、行政法规和规章,提出秸秆综合利用和禁烧管理的立法建议,为完善相关法规,从法律上保障秸秆综合利用水平的持续提高和秸秆禁烧管理工作的顺利开展提供相关建议。[方法]在系统梳理相关资料、文献的基础上,就国家现行法律和行政规章对秸秆综合利用的明文规定、对秸秆利用相关产业发展的规定进行综述,并就相关法律、规章对农作物秸秆禁烧的明文规定、秸秆禁烧治安管理和秸秆故意焚烧犯罪量刑的法律依据等进行归纳分析。最后,通过分析中国现行法规和行政指导文件在秸秆综合利用与秸秆禁烧管理方面存在的欠缺,提出必要的修订建议。[结果]随着时间的推移,我国法律对秸秆综合利用的规定日渐具体和完善。但直到目前,这些法律对秸秆综合利用的规定仍然缺失。有必要加快立法进程,完善相关法律、法规。[结论]建议对涉及秸秆利用方面的某些法规进行必要的修订;制定《耕地质量保护条例》,并将秸秆还田作为耕地质量保护的必要技术手段;对秸秆禁烧区外的秸秆限制焚烧从国家层面作出明确规定;借鉴国外经验,制定《生物质能条例》。     

基于GRA&BPNN的广西粮食产量预测研究

[目的]研究粮食产量的影响因素并以其相关性为基础预测粮食产量对实现广西粮食产业的"做强做优"具有重大意义。通常情况下粮食产量与种植技术发展水平、农田耕地面积、土地肥力、气候等诸多因素相关,但是在样本数据不足、数据间关联度不明显的情况下则无法采用回归分析、灰系统等常用预测方法。[方法]文章应用灰色关联分析方法得到水库水量、农田有效灌溉面积、第一产业从业人口、播种面积、除涝面积等5个与广西粮食产量关系最为密切的因子变量,同时取2004~2012年的数据作为学习、训练样本,以2013~2014年的数据为试报样本,并以此建立BP神经网络粮食预测模型。[结果]检验结果表明运用本模型预测粮食产量具有较高的精度和良好的泛化性。[结论]根据模型结果,该文提出提升广西粮食产业发展的可行性建议,即加强水库的管理、引导与粮食产业相关的产业、稳定粮食种植面积、加强洪涝灾害的防御和治理能力、推进农业信息化。

The retention ability of the agricultural landscape in the emergency planning zone of the Temelín nuclear power plant and its changes since the 19th century

Drainage and loss of wetland sites is a major problem of the agricultural landscape, as it reduces the landscape’s ability to retain water, nutrients, matter, and minimize erosion. With this in mind, the issue of the ability of wet sites to retain radionuclides and contaminated water in the case of a radiation accident was studied. In 2013, field research examined the occurrence of wetland retention sites in the emergency planning zone (EPZ) of the Temelín nuclear power plant (NPP; Czech Republic). As data sources, wetland biotopes (European network Natura 2000) were considered; in addition, retention features were field mapped, i.e. landscape elements of a wetland nature not normally considered nationally significant for conservation. Within the emergency zone, 2854.7 ha of wetland biotopes were registered and 318.9 ha retention features mapped. Density of retention sites (in ha/km²) per cadastre (local administrative units) was used to represent their spatial distribution within the zone. For an assessment of possible revitalization measures, leading to an increase in the landscape’s retention ability, spatial changes in the area of retention sites between 2013 and the mid-19th century, a period before extensive drainage of landscape occurred and a simplification of its structure, were mapped. Historic land maps (The Imperial Obligatory Imprints of the Stable Cadastre) were used as a basis of information on the occurrence and area of fens and wet meadows (4771.5 ha).For spatial comparisons of drained and undrained landscape in the past and present, the density of retention sites per cadastre was calculated. In the mid-19th century, 80% of cadastres had a density of retention sites exceeded 5 ha/km²; in 2013 only 40% of cadastres achieved this. In the most part, drained areas of the zone belong to the central part (around the power plant), as well as the EPZ’s eastern and south-eastern regions. From the density maps of retention sites, as well as from the stable cadastre imprints, it is possible to identify areas and retention features suitable for wetland restoration, thus leading to an increase in the retention capacity of the landscape in terms of water and radionuclide retention. Suggestions as to how to restore and turn retention features into semi-natural wetlands, as well as integrating small wetlands into an agriculture landscape are outlined.
