【摘要】：本文以岳陽(yáng)市岳陽(yáng)樓區(qū)為例,按照國(guó)土資源部部署的縣級(jí)耕地質(zhì)量等級(jí)評(píng)價(jià)工作,在2010年度耕地質(zhì)量等級(jí)補(bǔ)充完善成果基礎(chǔ)上,依據(jù)《農(nóng)用地質(zhì)量分等規(guī)程》(GB/T 28407-2012)和《湖南省耕地質(zhì)量等別更新評(píng)價(jià)技術(shù)手冊(cè)》技術(shù)方法,采用2013年度土地變更調(diào)查、農(nóng)村土地整治監(jiān)測(cè)監(jiān)管系統(tǒng)、耕地占補(bǔ)平衡系統(tǒng)等數(shù)據(jù),對(duì)2010-2013年度耕地質(zhì)量等別變化,開(kāi)展年度耕地質(zhì)量等別更新評(píng)價(jià)研究,在此基礎(chǔ)上,對(duì)結(jié)果進(jìn)行了分析。評(píng)價(jià)結(jié)果顯示,岳陽(yáng)樓區(qū)耕地從等別質(zhì)量所占百分比來(lái)說(shuō),總體質(zhì)量呈上升趨勢(shì)。該地區(qū)的耕地質(zhì)量建設(shè)項(xiàng)目已經(jīng)初見(jiàn)成效。但另一方面,由于該地區(qū)是岳陽(yáng)市的中心城區(qū),城鎮(zhèn)擴(kuò)張引起的耕地占用情況較明顯,新增耕地自然質(zhì)量等為8等,而減少耕地多為2等,在研究區(qū)域內(nèi)存在一定程度的占優(yōu)補(bǔ)劣情況,且新增耕地?cái)?shù)量上也大大低于減少耕地。從耕地質(zhì)量角度看,研究區(qū)域自然條件優(yōu)越,光、熱、水資源豐富,土壤有機(jī)質(zhì)含量較高,在2.0-4.0%之間,水田基本無(wú)障礙層次,旱地土壤有效土層厚度大多在60cm以上,土地生產(chǎn)潛力大。影響耕地質(zhì)量的障礙因素主要為：土壤質(zhì)地粘重,水田粘質(zhì)土壤面積占70%以上,旱地粘質(zhì)土壤面積占90%以上；土壤酸化退化明顯,pH值小于5.5的土壤面積占30%以上；土壤有機(jī)質(zhì)含量有下降趨勢(shì)。針對(duì)上述問(wèn)題,提出具有針對(duì)性的對(duì)策和建議,首先應(yīng)該做好城市土地利用規(guī)劃工作,從根本上控制現(xiàn)有耕地面積減少,積極補(bǔ)充耕地,達(dá)到耕地?cái)?shù)量動(dòng)態(tài)平衡的目標(biāo)。然后應(yīng)該加強(qiáng)農(nóng)田的基本建設(shè),多渠道提高土壤肥力,從而提高耕地質(zhì)量。從使用者來(lái)說(shuō),應(yīng)該普及教育農(nóng)民科學(xué)用肥,配方施肥,實(shí)現(xiàn)用地和養(yǎng)地相結(jié)合。研究成果為當(dāng)?shù)鼗巨r(nóng)田集中區(qū)的劃定、基本農(nóng)田整備區(qū)的劃定以及耕地保護(hù)補(bǔ)償機(jī)制的建立提供了科學(xué)的依據(jù)。
[Abstract]:Taking Yueyang Lou District of Yueyang City as an example, according to the evaluation work of cultivated land quality grade at the county level deployed by the Ministry of Land and Resources, and on the basis of the supplementary and perfect results of cultivated land quality grade in 2010, According to the Technical methods of "grading rules of Agricultural Land quality" (GB / T 28407-2012) and "Technical Manual for Evaluation of cultivated Land quality in Hunan Province", the data of land change investigation in 2013, monitoring and monitoring system of rural land regulation, and system of farmland occupation and compensation balance were adopted. Based on the evaluation of cultivated land quality and cultivated land quality in 2010-2013, the results are analyzed. The evaluation results show that the total quality of cultivated land in Yueyang Lou District is on the rise in terms of the percentage of equal quality. The cultivated land quality construction project in this area has already achieved initial results. But on the other hand, as this area is the central urban area of Yueyang City, the occupation of cultivated land caused by urban expansion is obvious, the natural quality of new cultivated land is 8, and the decrease of cultivated land is more than 2. In the study area, there are some advantages and disadvantages, and the amount of new cultivated land is much lower than that of reducing cultivated land. From the point of view of cultivated land quality, the natural conditions of the study area are superior, light, heat, abundant water resources, high content of soil organic matter, between 2.0% and 4.0%, paddy field is basically unobstructed layer, the thickness of effective soil layer of dryland soil is more than 60cm. Land production has great potential. The main factors affecting the quality of cultivated land are: soil texture and weight, soil area of paddy field clay more than 70%, dry land clay soil area more than 90%, soil acidification degradation and soil area with pH value less than 5.5 account for more than 30%. The content of soil organic matter decreased. In view of the above problems, the countermeasures and suggestions should be put forward. Firstly, the urban land use planning should be done well, the existing cultivated land area should be fundamentally controlled, the cultivated land should be actively supplemented, and the dynamic balance of cultivated land quantity should be achieved. Then we should strengthen the basic construction of farmland and improve soil fertility through multiple channels to improve the quality of cultivated land. As far as the users are concerned, farmers should be popularized and educated to use scientific fertilizer, formula fertilizer, and combine land use with cultivation land. The research results provide a scientific basis for the delineation of the local basic farmland concentration area, the demarcation of the basic farmland preparation area and the establishment of the compensation mechanism for the protection of cultivated land.
