【摘要】：隨著近年來金州區(qū)社會、經(jīng)濟(jì)的快速發(fā)展,各項(xiàng)建設(shè)大量的占用耕地,導(dǎo)致耕地?cái)?shù)量的減少,威脅金州區(qū)的糧食安全。此外,金州區(qū)一些地方土地的不合理開發(fā)利用,導(dǎo)致了環(huán)境問題的產(chǎn)生,破壞了當(dāng)?shù)氐纳鷳B(tài)平衡。金州區(qū)作為濱海城市,其生態(tài)環(huán)境特殊,在遼寧省的戰(zhàn)略布局中又處在重要的地位,對金州區(qū)進(jìn)行開發(fā)建設(shè),更應(yīng)該做到發(fā)展與環(huán)境的保護(hù)并舉。因此,對金州耕地后備資源進(jìn)行適宜性評價(jià),并做開發(fā)分區(qū)研究,有利于金州區(qū)耕地資源數(shù)量的增加,保障金州區(qū)的糧食安全,另一方面,金州區(qū)土地資源的定量分析評價(jià),是實(shí)際工作的要求,有利于資源的合理利用,對促進(jìn)金州區(qū)經(jīng)濟(jì)的可持續(xù)發(fā)展具有重要的現(xiàn)實(shí)意義。本文以大連市金州區(qū)為例,結(jié)合當(dāng)?shù)氐淖匀画h(huán)境和社會經(jīng)濟(jì)條件等,構(gòu)建了適合金州區(qū)的耕地后備資源評價(jià)指標(biāo)體系,結(jié)合ArcGIS技術(shù),得到金州區(qū)耕地后備資源適宜性評價(jià)結(jié)果。在此基礎(chǔ)上,參考金州區(qū)土地利用總體規(guī)劃等方面的資料,對金州區(qū)耕地后備資源的開發(fā)利用進(jìn)行分區(qū),并提出相應(yīng)的開發(fā)利用建議。本文在對金州區(qū)耕地后備資源進(jìn)行研究后,主要結(jié)論有:(1)本文結(jié)合了研究區(qū)域影響土地開發(fā)為耕地的內(nèi)部因素和外部因素,選取了合適的指標(biāo),基于GIS的空間疊加分析功能得到金州區(qū)耕地后備資源適宜程度圖層,結(jié)合土地利用總體規(guī)劃、大連市基本農(nóng)田保護(hù)規(guī)劃圖等用地規(guī)劃,對金州區(qū)耕地后備資源開發(fā)利用進(jìn)行分區(qū)。(2)金州區(qū)高度適宜的耕地后備資源多來源于沿海灘涂用地和其他草地,主要集中于金州區(qū)東部的杏樹街道、登沙河街道、大李家鎮(zhèn)沿海地帶;金州區(qū)中度適宜的耕地后備資源主要來源于其他草地和裸地,其主要分布在大魏家街道和登沙河街道,在華家屯鎮(zhèn)、杏樹街道、灣里街道和友誼街道也有部分分布,馬橋子街道沒有中度適宜耕地后備資源;金州區(qū)勉強(qiáng)適宜耕地后備資源主要來源于采礦用地和其他草地,其主要分布于金州區(qū)西北方向的七頂山街道和大魏家街道。(3)對金州區(qū)耕地后備資源開發(fā)時(shí)序進(jìn)行了分區(qū)。將金州區(qū)東北部杏樹街道、登沙河街道和大李家鎮(zhèn)三個(gè)地區(qū)的沿海地區(qū)至鶴大高速的地帶劃為近期重點(diǎn)開發(fā)區(qū);將金州區(qū)東北部的華家屯鎮(zhèn)、杏樹街道和登沙河街道的內(nèi)陸地區(qū)劃為中期開發(fā)區(qū);將七頂山街道、大魏家街道和得勝鎮(zhèn)、大李家鎮(zhèn)劃為遠(yuǎn)期開發(fā)區(qū)。(4)闡述了金州區(qū)目前耕地后備資源開發(fā)利用存在的問題。分析了開發(fā)利用過程中水土流失、灘涂利用粗放、農(nóng)用地非農(nóng)轉(zhuǎn)化等一些問題,并對今后的耕地后備資源開發(fā)利用提出了對策和建議。
[Abstract]:With the rapid development of society and economy in Jinzhou District in recent years, a large amount of cultivated land is occupied by various construction projects, which leads to the decrease of cultivated land quantity and threatens the food security of Jinzhou District.In addition, the unreasonable development and utilization of some local land in Jinzhou District resulted in environmental problems and destroyed the local ecological balance.As a coastal city, Jinzhou District has a special ecological environment and plays an important role in the strategic layout of Liaoning Province. The development and construction of Jinzhou District should be carried out simultaneously with the protection of the environment.Therefore, to evaluate the suitability of cultivated land reserve resources in Jinzhou, and to do research on development zoning, is beneficial to increase the amount of cultivated land resources in Jinzhou District and ensure the food security of Jinzhou District. On the other hand, the quantitative analysis and evaluation of land resources in Jinzhou District are beneficial to the increase of the amount of cultivated land resources in Jinzhou District.It is the requirement of practical work, is advantageous to the rational utilization of resources, and has important practical significance to promote the sustainable development of economy in Jinzhou district.Taking Jinzhou District of Dalian City as an example, combining with local natural environment and social and economic conditions, this paper constructs an evaluation index system of cultivated land reserve resources suitable for Jinzhou District. Combined with ArcGIS technology, the suitability evaluation results of cultivated land reserve resources in Jinzhou District are obtained.On this basis, with reference to the overall planning of land use in Jinzhou District, the development and utilization of cultivated land reserve resources in Jinzhou District are divided, and the corresponding suggestions for development and utilization are put forward.After studying the reserve resources of cultivated land in Jinzhou District, the main conclusions are as follows: (1) this paper combines the internal and external factors that influence the land development in the research area, and selects the appropriate indexes.Based on the spatial superposition analysis function of GIS, the suitability level of cultivated land reserve resources in Jinzhou district is obtained. Combined with the overall land use planning, the basic farmland protection planning map of Dalian is used for land planning.Development and utilization of cultivated land reserve resources in Jinzhou District. 2) the highly suitable cultivated land reserve resources in Jinzhou District are mostly derived from coastal beach land and other grasslands, and are mainly concentrated in the Xingshu Street and Dengsha River Street in the east of Jinzhou District.The reserve resources of moderately suitable cultivated land in Jinzhou District mainly come from other grasslands and bare land, which mainly distribute in the streets of Dawei and Dengsha River, in Huajatun Town, and in the streets of Apricot trees.Wan Li Street and Friendship Street are also partially distributed, Ma Qiao Zi Street has no moderately suitable cultivated land reserve resources; Jinzhou District barely suitable arable land reserve resources mainly come from mining land and other grasslands.It is mainly distributed in Qidingshan Street and Dawejia Street, northwest of Jinzhou District, and the time series of cultivated land reserve resources development in Jinzhou District has been divided.The three coastal areas of Jinzhou District, northeast of Jinzhou District, Xingshu Street, Dengsha River Street and Da Li Zhen, from coastal areas to Heda Expressway, will be designated as key development zones in the near future; Huajatun Town, northeast of Jinzhou District, will be designated as a key development zone.The inland area of Xingshu Street and Dengsha River Street is designated as the medium term Development Zone, and the Qidingshan Street, Da Wei Jia Street and Desheng Town are designated as forward Development Zone .4) the problems existing in the exploitation and utilization of cultivated land reserve resources in Jinzhou District are expounded.Some problems such as soil and water loss, extensive use of tidal flat and non-agricultural transformation of agricultural land in the process of development and utilization are analyzed, and countermeasures and suggestions for the development and utilization of reserve resources of cultivated land in the future are put forward.
