【摘要】：21世紀(jì)，隨著人口迅猛增長和社會經(jīng)濟(jì)發(fā)展，在人類面臨的眾多危機(jī)中，糧食危機(jī)對于人口第一大國的中國顯得尤為明顯，人地矛盾日益突出。耕地后備資源的開發(fā)是解決人地矛盾的一個重要途徑，有助于社會經(jīng)濟(jì)生活的可持續(xù)發(fā)展，是貫徹和實踐科學(xué)發(fā)展觀的重要體現(xiàn)。耕地對于保障國家糧食安全和社會穩(wěn)定發(fā)展具有戰(zhàn)略意義，而耕地后備資源作為耕地的重要補(bǔ)充來源，對其進(jìn)行開發(fā)于國民經(jīng)濟(jì)穩(wěn)定發(fā)展具有重大的現(xiàn)實意義。 本文在研究分析了耕地后備資源及其開發(fā)潛力的基礎(chǔ)上，討論了耕地后備資源開發(fā)潛力評價的理論基礎(chǔ)及其評價體系的建立。以陜西省延安市吳起縣為例，對現(xiàn)有的耕地資源進(jìn)行分析后，，利用特爾菲法和層次分析法相結(jié)合的方法綜合確定了坡度、坡向、土層厚度、水源、交通便捷程度和居民點等6個參評因子并確定其權(quán)重，運用ArcGIS軟件的空間分析、緩沖區(qū)分析、疊加分析等分析方法對吳起縣耕地后備資源開發(fā)潛力進(jìn)行分析評價，對各參評因子分等賦值，最后再利用綜合指數(shù)法進(jìn)行綜合評價分析，從而構(gòu)建多因素綜合評價指標(biāo)模型，分析得出研究區(qū)的耕地后備資源的數(shù)量、質(zhì)量以及空間分布格局，對全縣可供開發(fā)的耕地后備資源分為近期開發(fā)、中期開發(fā)、遠(yuǎn)期開發(fā)三個級別。為調(diào)整和優(yōu)化土地利用結(jié)構(gòu)，制定合理的土地開發(fā)利用規(guī)劃提供了科學(xué)的理論基礎(chǔ)和參考依據(jù)。
[Abstract]:In the 21st century, with the rapid growth of population and the development of social economy, among the many crises facing mankind, the food crisis is especially obvious for China, which has the largest population, and the contradiction between man and land is becoming more and more prominent. The development of cultivated land reserve resources is an important way to solve the contradiction between man and land, is conducive to the sustainable development of social and economic life, and is an important embodiment of carrying out and practicing the scientific concept of development. Cultivated land is of strategic significance for ensuring national food security and social stability. As an important supplementary source of cultivated land, it is of great practical significance to develop cultivated land reserve resources in the stable development of national economy. Based on the study and analysis of the cultivated land reserve resources and their exploitation potential, this paper discusses the theoretical basis and the establishment of the evaluation system of the cultivated land reserve resources development potential. Taking Wuqi County, Yan'an City, Shaanxi Province as an example, after analyzing the existing cultivated land resources, the slope, slope direction, soil layer thickness and water source are determined synthetically by the combination of Delphi method and Analytic hierarchy process (AHP) method. Six factors, such as traffic convenience and residential area, are evaluated and their weights are determined. By using the spatial analysis, buffer analysis and superposition analysis of ArcGIS software, the potential development potential of cultivated land reserve resources in Wuqi County is analyzed and evaluated. Finally, the comprehensive evaluation analysis is carried out by using the comprehensive index method to construct the multi-factor comprehensive evaluation index model, and the quantity, quality and spatial distribution pattern of the cultivated land reserve resources in the study area are obtained. The reserve resources of cultivated land available for development in the whole county are divided into three levels: short-term development, medium-term development and long-term development. It provides a scientific theoretical basis and reference basis for adjusting and optimizing the land use structure and making rational land development and utilization planning.
