神府-东胜矿区在特定的自然地质环境和人为因素的影响下,土地沙漠化呈不断扩展的演化趋势。矿区大规模的开发建设,更加速了沙漠化进展。本文利用典型地段的沙漠化发展速率,依据矿区总体设计规模,对矿区自然沙漠化趋势和开矿新增沙漠化土地面积进行了定量预测,并提出了相应的防治措施。 相似文献

中国国家十二五规划纲要提出要实施主体功能区战略。日本针对经济发展过程中产生区域问题所采取的6次全国国土综合开发规划的财政政策,值得借鉴。中国在推进主体功能区建设过程中,应当运用差别化税收政策引导重点开发区域承接优化开发区域的产业转移,加大对重点开发区域基础设施的投入,发挥财政转移支付制度对地方财力的平衡作用。 相似文献

Land rental market, off-farm employment and agricultural production in Southeast China: A plot-level case study 总被引:1,自引:0,他引:1
This paper performs a plot-level analysis of the impact of land rental market participation and off-farm employment on land investment, input use, and rice yields for 215 plots cultivated by 52 households in three villages in Northeast Jiangxi Province. Our findings show that households that rent extra land are relatively more productive, but contradict results of earlier studies which found that tenure status of plots affects the level of land investments. We further find that off-farm employment does not significantly affect rice yields. This result contradicts those of earlier studies which found that the negative lost-labor effect of off-farm employment dominates the positive income effect. Another novel finding is that people working locally off-farm tend to switch from green manure planting towards the use of organic manure on their rice plots. We conclude that policies that will further stimulate the development of land rental markets, which is still in its infancy, can contribute significantly to higher rice production in Southeast China. Another implication of our results is that worries about the negative impact that the continuously growing off-farm employment may have on China's goal to remain self-sufficient in grain production are less relevant at the moment for the region examined in our study. 相似文献

为矫正土地出让金实际支出中的"重城轻农"倾向,国家相关文件原则性规定了土地出让金的五种支出方向,但并未给出各支出方向的具体比例。基于广州市土地出让金利益相关者对各支出方向相对重要性排序的495份调查问卷,采用相对熵组合赋权方法测算土地出让金各支出方向的具体比例。研究表明,土地出让金用于城市建设、支农、土地开发、征地拆迁补偿、其他支出的合理比例应分别为19.51%、21.35%、18.88%、19.15%、21.11%;其中支农支出比例最高,支农支出与征地拆迁补偿支出比例合计达40.50%,与土地出让金支出"重点向新农村建设倾斜"的政策契合。在土地出让金支出重点向新农村建设倾斜的大前提下,可制定土地出让金各支出方向比例的合理区间给地方政府预留一定的弹性操作空间;建立土地收益基金等措施维护上下届政府间的"代际公平"。要确保土地出让收益用于农民、农业、农村,还可参照目前土地复垦净收益分配方式,硬性规定土地被征收前的土地所有权人与土地使用权人占土地出让净收益的一定比例。 相似文献

In the search for solutions to complex real-world problems, the benefits of transdisciplinary research (TDR) have been widely heralded. Land use science appears to be a designated field for TDR. However, to date, the additional expenses of TDR are accompanied by a so far not proved added value, and empirical findings are claimed to be scarce and dispersed over several disciplines and case studies.We reviewed 299 articles obtained from a structured literature search to (1) investigate the current differences between theory and practice, (2) identify empirical findings, and (3) ascertain the contributions of TDR to promoting sustainable land use management.Our results demonstrate that, in spite of an increasing conceptual consistency in the theoretical discussion of TDR, the implementation of TDR remains a substantial challenge, in part because of the gap between theory and practice. In addition, research on TDR is science and process centred. The benefits of TDR in addressing real-world problems within the field of land use remain unproven. 相似文献

Understanding spatial patterns of visitation and benefits accrued to different types of natural and cultural heritage tourists may have important implications for the sustainable management of their destinations. We investigate cultural services accrued to local, domestic and international visitors to the Usumacinta floodplain, a coastal region with one of the highest biological and cultural diversities in Mexico. We combine analysis of social media photographs and high-resolution land cover mapping to identify different cultural services and their association with specific ecosystem and land cover types. Hotspots for international tourists are spatially restricted to well-known and accessible sites. Locals are 2.2–2.5 times more likely than international visitors to be associated with aesthetic appreciation and birdwatching. Locals upload more photographs of coastal lagoons, mangroves, beach and sea. Results are analyzed in light of land cover changes in the region and provide valuable information to decision makers for improved tourism management and conservation strategies. 相似文献

通过实证考察湖北、贵州两省近几年农村土地承包经营权流转的现状及对其成因的探析可以发现,中西部地区的农村要达致土地承包经营权规模化经营的理想状态,还有诸多制约因素有待克服。破解之道主要在于应构建有利于促进土地承包经营权流转的配套制度,营造有利于土地承包经营权流转的社会条件和经济环境。 相似文献
