4.5 Protect untouched arable land resources and reclaim orderly
Wasteland suitable for farming constitutes major untouched arable land resources. Withthe acceleratioof urbanizatioand industrializatioprocesses iChina and rapid progressithe infrastructure construction, it is necessary to substantially strengthethe protectioofwasteland suitable for farming and avoid destructive development. While maintaining the quan-tity of untouched arable land resources, more attentioshould be paid to the conservatioof theeco-environment around the untouched arable land (Che2001). We should encourage andsupport farmers and flagship enterprises, under the preconditioof not degrading eco-environ-ment, to invest more ireclaiming the wasteland suitable for farming, increase input, built itinto stable and high yield cropland and incorporate it into the category of capital farmland forprotectioaccording to law.
Besides, with respect to the methods and priority for arable land protectioiChina, dif-ferent measures should also be adopted iline with the regional difference iland resources: As.the farmland is good iquality and high iyield ithe eastercoastal region, land consolidationshould be carried forward vigorously othe basis of more effective protectioof existing capitalfarmland iorder to improve agro-productioconditions, upgrade farmland quality and yieldand increase acreage; Through city land consolidation, intensive land use should be promotedand the pressure ing from use of farmland for non-agricultural purposes due to rapid devel-opment of regional economy and urbanizatiobe eased. At the same time the agricultural pro-ductiostructure should be optimized and othe prerequisite of not damaging the topsoil, labor-intensive productioand processing with advanced technology should be carried out to increasethe added value and petitiveness of farm produce.
The middle region, featured by a large quantity of arable land, ideal sunshine and tempera-ture and good land utilization, is the basis to ensure our nation's food security. But ithis re-gioa large part of farmland suffers from natural hazards including drought, flood and saliniza-tioand the medium- and low-yield land is distributed extensively. Therefore the emphasisshould be shifted from maintenance of acreage to yield. Except for key protectioof high-yieldfertile farmland, prehensive treatment of medium- and low-yield fields should be enhancedto buffer the harm of natural calamities and increase the overall productiocapacity of farmland(Tiaet a/. 2002) .

这本书的标题就让我眼前一亮:《9787502943776 中国耕地土壤有机碳储量变化及其对粮食安全影响的模拟研究(英文版)》。在当前全球气候变化和粮食安全日益受到重视的背景下,这本书似乎直击核心问题。我一直对土地利用、气候变化与农业生产之间的复杂联系深感兴趣,尤其是土壤有机碳作为衡量土壤健康和固碳潜力的关键指标,其变化规律和对粮食产量的影响,绝对是一个值得深入探讨的课题。想象一下,当我们能够更精确地预测土壤有机碳的变化趋势,并将其与粮食生产的潜在风险联系起来,这对于制定更具前瞻性的农业政策、优化耕作方式、甚至推动碳汇农业的发展,都将具有不可估量的价值。这本书的英文版,也预示着它可能吸收了国际上最新的研究成果和方法,并可能为国际学术界提供中国在这一领域的宝贵数据和经验。我非常期待它能带来一些颠覆性的洞见,帮助我们理解中国这片广袤土地上正在发生的深刻变革,以及这些变革将如何塑造我们未来的粮食供应。
评分这本书的英文版名称——《9787502943776 中国耕地土壤有机碳储量变化及其对粮食安全影响的模拟研究》——立刻勾起了我的阅读兴趣。在当今世界,粮食安全和气候变化是两个紧密相连且至关重要的议题,而土壤有机碳作为连接这两者的关键节点,其研究价值不言而喻。我尤其关注的是,这本书的“模拟研究”部分,它意味着作者不仅仅是在回顾和分析历史数据,更是在尝试建立一个预测模型。这对于我们理解未来可能发生的变化,并提前采取应对措施至关重要。我期望书中能够提供关于其模拟模型的详细介绍,包括所使用的软件、算法,以及模型的精确度如何被评估。更让我好奇的是,研究是如何将土壤有机碳储量的变化与“粮食安全”这一更为宏观的概念联系起来的。书中是否会探讨,例如,有机碳下降是否会削弱土壤的保水保肥能力,进而影响作物产量和质量?或者,通过提高土壤有机碳含量,是否能够增强农田的固碳能力,为应对气候变化做出贡献?我希望这本书能够提供一些具体的、基于数据的分析,来展示这种内在联系的量化程度。例如,是否会有不同情景下的模拟结果,展示在不同耕作措施下,土壤有机碳变化对特定作物(如水稻、小麦)产量产生的具体影响?
评分作为一个对农业科技和可持续发展领域抱有浓厚兴趣的读者,这本书的题目《9787502943776 中国耕地土壤有机碳储量变化及其对粮食安全影响的模拟研究(英文版)》立刻吸引了我的目光。首先,“中国耕地”这个限定词,让我觉得这项研究具有极强的现实意义和地域针对性。中国是世界上面积最大的发展中国家,也是人口最多的国家,耕地资源极其宝贵,粮食安全更是国家发展的基石。土壤有机碳是土壤肥力的重要来源,也是一个巨大的碳库,其动态变化不仅影响着耕地的可持续利用,也与应对全球气候变化息息相关。我特别希望书中能够深入剖析中国不同区域、不同类型耕地的土壤有机碳储量现状,以及导致这些储量变化的驱动因素,是自然因素(如气候、地形)还是人为因素(如耕作方式、施肥施药、土地休耕等)。而“模拟研究”的定位,则暗示着这本书将运用先进的计算模型和数据分析技术,来预测未来的趋势和评估潜在的影响。我非常期待作者能够详细阐述其模拟模型的构建过程,包括数据来源、模型假设、以及模型验证方法,希望能看到一些具体的研究结果,比如在不同政策干预下,或者在不同气候情景预测下,土壤有机碳储量变化对粮食产量可能产生的量化影响。
评分坦白讲,我对“土壤有机碳”这个概念的理解,更多停留在教科书式的层面,知道它对土壤肥力、固碳能力至关重要,但具体到“储量变化”及其“对粮食安全影响”的模拟研究,就显得颇具深度了。这本书的出现,正是我想要填补这一知识空白的绝佳机会。我好奇作者是如何量化“土壤有机碳储量”的?是采用土壤采样分析,还是基于遥感数据推算,或者两者结合?而“变化”又是指多长时间尺度的变化?是年度变化、十年尺度,还是更长期的趋势?书中是否会提供具体的案例分析,来展示不同地区、不同耕作方式下的土壤有机碳储量的具体变化情况?例如,东北黑土地的有机碳流失,与南方水稻田的有机碳积累,是否存在显著差异,以及这些差异对当地粮食生产带来了怎样的影响?更让我感兴趣的是,当这些变化被模拟出来后,它们与“粮食安全”之间是如何建立起清晰的联系的。比如,有机碳下降是否直接导致土壤肥力下降,从而影响作物产量?或者,有机碳储量增加是否能增强土壤的抗旱、抗涝能力,从而提升粮食生产的稳定性?这本书能否为我们揭示一些中国耕地在面临气候变化和高强度农业生产双重压力下,土壤健康状况的真实图景,并为守护中国的“饭碗”提供科学的依据?
评分对于一本以“模拟研究”为核心的书籍,我总是充满好奇。这意味着它不仅仅是陈述事实,更是在试图构建一个能够预测未来的模型。尤其是在探讨“中国耕地土壤有机碳储量变化及其对粮食安全影响”这样一个宏大的主题时,模型的精准度和可靠性就显得尤为重要。我希望这本书能够详细介绍其所采用的模拟方法,例如是基于统计学模型、过程模型,还是机器学习模型?模型的输入参数又包含了哪些关键变量?例如,气温、降雨量、施肥量、秸秆还田情况,甚至是土地管理政策的调整,这些是如何被纳入模型的?更重要的是,作者是如何验证模型的准确性的?是否使用了历史数据进行回溯分析,或者通过实地试验进行校准?我特别关注的是,模型在预测土壤有机碳变化时,能够细化到什么样的空间尺度?是全国性的粗略估计,还是能够深入到省级、地市级,甚至更精细的耕作单元?而当这些模拟结果与粮食安全挂钩时,作者又是如何量化这种联系的?是通过粮食产量预测模型,还是通过分析粮食可获得性、可负担性和利用性等多个维度?我对书中可能提出的各种情景分析也充满了期待,比如在不同气候变化情景下,或者在不同农业管理策略下,土壤有机碳储量和粮食产量会发生怎样的变化?
