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) .

這本書的標題就讓我眼前一亮:《9787502943776 中國耕地土壤有機碳儲量變化及其對糧食安全影響的模擬研究(英文版)》。在當前全球氣候變化和糧食安全日益受到重視的背景下,這本書似乎直擊核心問題。我一直對土地利用、氣候變化與農業生産之間的復雜聯係深感興趣,尤其是土壤有機碳作為衡量土壤健康和固碳潛力的關鍵指標,其變化規律和對糧食産量的影響,絕對是一個值得深入探討的課題。想象一下,當我們能夠更精確地預測土壤有機碳的變化趨勢,並將其與糧食生産的潛在風險聯係起來,這對於製定更具前瞻性的農業政策、優化耕作方式、甚至推動碳匯農業的發展,都將具有不可估量的價值。這本書的英文版,也預示著它可能吸收瞭國際上最新的研究成果和方法,並可能為國際學術界提供中國在這一領域的寶貴數據和經驗。我非常期待它能帶來一些顛覆性的洞見,幫助我們理解中國這片廣袤土地上正在發生的深刻變革,以及這些變革將如何塑造我們未來的糧食供應。
評分對於一本以“模擬研究”為核心的書籍,我總是充滿好奇。這意味著它不僅僅是陳述事實,更是在試圖構建一個能夠預測未來的模型。尤其是在探討“中國耕地土壤有機碳儲量變化及其對糧食安全影響”這樣一個宏大的主題時,模型的精準度和可靠性就顯得尤為重要。我希望這本書能夠詳細介紹其所采用的模擬方法,例如是基於統計學模型、過程模型,還是機器學習模型?模型的輸入參數又包含瞭哪些關鍵變量?例如,氣溫、降雨量、施肥量、秸稈還田情況,甚至是土地管理政策的調整,這些是如何被納入模型的?更重要的是,作者是如何驗證模型的準確性的?是否使用瞭曆史數據進行迴溯分析,或者通過實地試驗進行校準?我特彆關注的是,模型在預測土壤有機碳變化時,能夠細化到什麼樣的空間尺度?是全國性的粗略估計,還是能夠深入到省級、地市級,甚至更精細的耕作單元?而當這些模擬結果與糧食安全掛鈎時,作者又是如何量化這種聯係的?是通過糧食産量預測模型,還是通過分析糧食可獲得性、可負擔性和利用性等多個維度?我對書中可能提齣的各種情景分析也充滿瞭期待,比如在不同氣候變化情景下,或者在不同農業管理策略下,土壤有機碳儲量和糧食産量會發生怎樣的變化?
評分這本書的英文版名稱——《9787502943776 中國耕地土壤有機碳儲量變化及其對糧食安全影響的模擬研究》——立刻勾起瞭我的閱讀興趣。在當今世界,糧食安全和氣候變化是兩個緊密相連且至關重要的議題,而土壤有機碳作為連接這兩者的關鍵節點,其研究價值不言而喻。我尤其關注的是,這本書的“模擬研究”部分,它意味著作者不僅僅是在迴顧和分析曆史數據,更是在嘗試建立一個預測模型。這對於我們理解未來可能發生的變化,並提前采取應對措施至關重要。我期望書中能夠提供關於其模擬模型的詳細介紹,包括所使用的軟件、算法,以及模型的精確度如何被評估。更讓我好奇的是,研究是如何將土壤有機碳儲量的變化與“糧食安全”這一更為宏觀的概念聯係起來的。書中是否會探討,例如,有機碳下降是否會削弱土壤的保水保肥能力,進而影響作物産量和質量?或者,通過提高土壤有機碳含量,是否能夠增強農田的固碳能力,為應對氣候變化做齣貢獻?我希望這本書能夠提供一些具體的、基於數據的分析,來展示這種內在聯係的量化程度。例如,是否會有不同情景下的模擬結果,展示在不同耕作措施下,土壤有機碳變化對特定作物(如水稻、小麥)産量産生的具體影響?
評分坦白講,我對“土壤有機碳”這個概念的理解,更多停留在教科書式的層麵,知道它對土壤肥力、固碳能力至關重要,但具體到“儲量變化”及其“對糧食安全影響”的模擬研究,就顯得頗具深度瞭。這本書的齣現,正是我想要填補這一知識空白的絕佳機會。我好奇作者是如何量化“土壤有機碳儲量”的?是采用土壤采樣分析,還是基於遙感數據推算,或者兩者結閤?而“變化”又是指多長時間尺度的變化?是年度變化、十年尺度,還是更長期的趨勢?書中是否會提供具體的案例分析,來展示不同地區、不同耕作方式下的土壤有機碳儲量的具體變化情況?例如,東北黑土地的有機碳流失,與南方水稻田的有機碳積纍,是否存在顯著差異,以及這些差異對當地糧食生産帶來瞭怎樣的影響?更讓我感興趣的是,當這些變化被模擬齣來後,它們與“糧食安全”之間是如何建立起清晰的聯係的。比如,有機碳下降是否直接導緻土壤肥力下降,從而影響作物産量?或者,有機碳儲量增加是否能增強土壤的抗旱、抗澇能力,從而提升糧食生産的穩定性?這本書能否為我們揭示一些中國耕地在麵臨氣候變化和高強度農業生産雙重壓力下,土壤健康狀況的真實圖景,並為守護中國的“飯碗”提供科學的依據?
評分作為一個對農業科技和可持續發展領域抱有濃厚興趣的讀者,這本書的題目《9787502943776 中國耕地土壤有機碳儲量變化及其對糧食安全影響的模擬研究(英文版)》立刻吸引瞭我的目光。首先,“中國耕地”這個限定詞,讓我覺得這項研究具有極強的現實意義和地域針對性。中國是世界上麵積最大的發展中國傢,也是人口最多的國傢,耕地資源極其寶貴,糧食安全更是國傢發展的基石。土壤有機碳是土壤肥力的重要來源,也是一個巨大的碳庫,其動態變化不僅影響著耕地的可持續利用,也與應對全球氣候變化息息相關。我特彆希望書中能夠深入剖析中國不同區域、不同類型耕地的土壤有機碳儲量現狀,以及導緻這些儲量變化的驅動因素,是自然因素(如氣候、地形)還是人為因素(如耕作方式、施肥施藥、土地休耕等)。而“模擬研究”的定位,則暗示著這本書將運用先進的計算模型和數據分析技術,來預測未來的趨勢和評估潛在的影響。我非常期待作者能夠詳細闡述其模擬模型的構建過程,包括數據來源、模型假設、以及模型驗證方法,希望能看到一些具體的研究結果,比如在不同政策乾預下,或者在不同氣候情景預測下,土壤有機碳儲量變化對糧食産量可能産生的量化影響。
