关于我国征地制度问题的研究

城镇化作为农民职业转换、身份转变和社会价值观转型的载体,其健康发展成为解决中国"三农"问题的核心之所在。目前我国城镇化正处在发展推进期,传统的征地制度日渐显现出其内在的弊端,甚至蜕变为我国城镇化发展中的障碍因素。因此,有必要在廓清我国征地制度的变迁轨迹的基础上,剖析传统征地制度中存在的固有缺陷,为探明相应的制度变迁路径提供一种思路。     

土地资源开发利用的生态自然观刍议

土地资源的有限性和需求的无限增长性,是人类社会经济发展过程中一对难以调和的矛盾,而且这对矛盾长期以来被人们忽略,从而对实现土地资源可持续利用造成了一定程度的影响.文章从自然观演进的角度,分析不同阶段土地资源开发利用的自然观特征;针对当前我国土地资源开发利用现状,提出生态自然观是我们应该积极倡导的一种理想的土地资源开发利用自然观,并对土地资源开发利用生态自然观的理论基础、核心内容和实践形式等进行了探讨.     

土地资源可持续发展的一个潜在危机

殡葬改革的初衷是不留骨灰,不占土地.但改革开放以来,在市场经济的拉动下,后火化过程异军突起,以墓地为标志的殡葬消费不断高扬,白色地甲不断蔓延,危害了土地生态的可持续发展.然而由于殡葬和土地资源归属于两个不同的部门和学科,这种深刻的生态危机一直未能引起社会和学界的普遍关注.本文通过对殡葬管理历史和现实的分析,提出在两种体制并存的条件下加强对后火化过程的强干预,引导殡葬消费,弘扬入土为安的中华文明,发展生态墓地和可降解殡葬用品,探讨殡葬管理的社会福利功效,把是否有利于土地资源的可持续发展作为殡葬管理的根本目标.     

干旱地区生态补偿制度建立的未来学研究

近年来,我国生态环境不断恶化,这一发展态势在干旱地区表现得更为明显.我国政府为了尽快改善生态环境,相继制定了一系列生态补偿政策.但由于没有针对干旱地区具体情况的专门补偿措施,所以在实际执行过程中相关利益人补偿得不到及时体现的现象时有发生.这些问题需要我们加以研究并且提出符合干旱地区自有特征以及未来发展状况的生态补偿制度,只有这样才能真正解决干旱地区目前的生态补偿困境,完善我国干旱地区未来学研究体系,实现兴利除弊.     

湖南省各地市州农作物总产量比较分析

农作物产量与自然条件息息相关,并且直接关系到湖南省的综合发展,本文分别从气温、降水、日照时数、耕地面积4个指标对湖南省14个地市州进行全面测度和比较;运用主成分分析法分析因子的贡献率和各因子载荷量。结果表明农作物总产量搞的是常德、衡阳、邵阳;而张家界、湘西农作物产量低。     

A study of virtual land trade between China and ASEAN based on material flow analysis model

In this paper,based on the material flux analysis model（MFA） and its corresponding theories and algorithms of ＂virtual land＂ virtual land contents of five primary agricultural products are calculated and＂Virtual land trade＂hidden in those imported and exported products are also obtained through analyzing the primary agricultural product trade between China and ASEAN. In the process of calculationl following the thought of Changing agricultural products to ＂Virtual land trade＂land content, trade condition and spatiai distribution of agricultural products Were integratedly considered. indicate that China exported 73;057 km^2 of virtual land area to ASEAN by tea, vegetables; maize and grain, ASEAN exported： 57.332 km^2 to China by natural rubber from 2002 to 2005. It obvious; that china has lost 15,725 km^2 arable land through agricultural product trade, Additionally, in order to process： of calculation Virtual land trade, Thailand taker as an example to analyze its international trade of rice and Wheat from 1991 to 2005 and Calculate their ＂Virtual land trade＂ 2001 through 2005. According to and calculation, it is not difficult to conclude that ＂Virtual land trade＂ very important and could be used for China to guide agricultural export or import Structure and maintain Sustainable use of land resources.     

Analysis of nutrient content and assessment of economic value for major salt-tolerant plants in coastal areas: a case study of Dongying City,Shandong Province

Salinization of soil is a worldwide problem concerning resources and ecology,especially serious in coastal areas.Testing of 26 sorts of data or parameters are carried out on leaves of 22 plant species (in 24 plant variety) of existing main salt-tolerant plant of the Yellow River Delta region.Data or parameters include the following elements:contents of K+,Na+,Ca2+,Mg2+ and Cl-,contents of protein,fat,total energy,ash and contents of 17 amino acids.The results show that these tested plants have economic values.For example,according to their uses,they can be divided into edible plants,forage plants,medicine or health plants,and some of them can be used for multipurposes.These plants have played important roles in the sustainable utilization of plant resources in coastal areas.This paper has taken evaluations on the economic uses of salt-tolerant plants and given suggestions for saline soil improvement and resource utilization in coastal areas.Based on the results of investigation and experiments,we suppose that the salt-tolerant plants in coastal areas can be grouped into 9 main groups according to their eeonomic value:pioneer plants for saline land improvement,medicine,edible and forage plants,industry material forestation,breeding material,energy plants and eco-tourism resources.     

采煤塌陷地复垦投资机制研究

在我国的煤炭开采生产中,造成的土地破坏以塌陷地为主,大部分塌陷地需要恢复治理后才能重新利用。在我国,耕地资源繁缺,为改善生态环境,保护耕地,国家加大了土地复垦工作的力度。但是,塌陷地复垦的投资机制不完善,制约着复垦工作的顺利进行。立足采煤塌陷地复垦的投资机制现状,从资金管理制度、复垦土地产权、建立塌陷地复垦市场体系、完善政策法规着手,完善采煤塌陷地复垦投资机制。     

地方政府土地违法行为探析

土地,是人类赖以生存的基础。时至今日,随着人类认识和改造自然能力的增强,土地已成为食物生产、经济发展和生态环境建设“争夺”的焦点。各类“中国特色”的土地违法案件层出不穷,其中以地方政府土地违法问题最为突出。因此,从体制、机制、法制的角度认识和完善当前我国地方政府土地违法行为已成为亟待解决的问题。     

农村集体建设用地产权问题及其成因

随着中国工业化和城市化步伐的加速,土地的资产价值已为人们所认识并加以利用,农村集体建设用地产权问题也日益成为人们关注的焦点。中国现有农村集体建设用地产权制度的实施状况,说明这一制度安排的实施绩效并未完全达到立法者的预期目标。其原因可归结为：城乡分割的二元土地制度以及政府对土地市场的垄断,农村集体用地所有权主体模糊,使用权主体不确定以及产权权能不清。
