摘要
人口與耕地資源的關系研究是社會經濟發展特別是農業發展的重要課題。人一方面是生產資料的擁有者,可以推動社會經濟的進步,另一方面作為生產資料的消費者,對糧食產量提出高要求。隨著我國經濟的高速發展,人們對糧食的需求也在日益增加。糧食的生產依附于耕地資源,對耕地資源的保護可以有效的緩解由糧食問題帶來的人地矛盾。影響耕地安全的因素有很多,包括政策因素、農業因素、自然因素和人口因素,其中人口因素是影響耕地安全的最重要的因素。
解決好人口流動對耕地資源安全的影響,不僅可以保護耕地資源,而可以促進人與自然的和諧相處,最終達到可持續發展的目標。
清水江位于貴州省的東南部,是洞庭湖沅水水系的上游干流。源于黔南州的都勻市,流經黔南、黔東南州的 16 個縣市和一個經濟開發區,省內河長 452.2km,流域面積 17145 平方公里,是貴州省境內的第二大江。清水江流域是少數民族的聚集地,有包括苗族、侗族、布依族在內的 33 個民族,主要以農業生產為主,生產的糧食中又以種植水稻為主。當地的生態環境雖好,但是是典型的生態脆弱區,土地經過長期的過度開發利用,已經對糧食的生產產生影響。作為糧食的載體,耕地資源的可持續發展受到阻礙。近幾年,在省外經濟驅動和省內其他地區工業化發展等因素的驅動下,清水江流域的居民大多外出打工,成為人口輸出地。
由于人口的大量流動,引發了耕地利用方式的變化,進而對當地的耕地資源安全產生影響。
本文根據清水江流域的人口流動現狀和耕地資源利用現狀的概述,總結人口流動的歷史過程和根本原因,發現人口的流動勢必會導致當地少數民族傳統耕作方式的變遷,運用環境經濟學和可持續發展的相關理論成果,對由耕作方式引起的耕地數量和質量的減少,探究人口流動對耕地資源的安全影響,最后,提出了耕地資源可持續發展的相關政策建議。希望通過對耕地資源安全影響因素的分析,對耕地保護機制的完善提供參考。

Abstract
Study on the relationship between the population and cultivated land resources isan important topic of the development of social economic development, especially inagriculture. On the one hand, people is the owner of production materials, canpromote the progress of social economy, on the other hand, as consumers of means ofproduction, puts forward higher requirements to food production. With the rapiddevelopment of China's economy, people's demand for food is increasing. Foodproduction attached to the cultivated land resources, the protection of cultivated landresources can effectively alleviate the contradictory between people and the landresources brought by food problem. There are many factors influencing the cultivatedland security, the policy factors, agricultural factors, natural factors and human factors,the most important factors affecting the safety of cultivated land is the populationfactor. To solve the population flow influence on cultivated land resource security, notonly can protect cultivated land resources, but can promote the harmony betweenhuman and nature, finally achieve the goals of sustainable development.
Qingshui river is situated in the southeast of Guizhou Province, is the dongtinglake river upstream of Yuan river water system. Is the result of Qiannan DouYun city,through the trait, 16 counties of Qiandongnan prefecture, and an economicdevelopment zone, province river 452.2 km long, watershed area of 17145 squarekilometers, is the second river in Guizhou Province. Qingshui river is an attractiveplace for ethnic minorities, including miao, dong, buyi, mainly in agriculturalproduction, the production of food is mainly rice. The local ecological environment isgood, but is a typical ecologically fragile area, land through long-term excessiveexploitation and utilization, has an effect on the production of food. As the carrier offood, the sustainable development of the cultivated land resources. In recent years, thedomestic economic drivers and other areas in the province industrialization driven byfactors such as the residents of the Qingshui river basin mostly migrant workers, aspopulation output. Due to the large number of mobile population, triggers thecultivated land use changes in the way, and then affect local cultivated land resourcesecurity.
In this paper, according to the situation of the population flow of Qingshui riverbasin and overview of cultivated land resource utilization, summarizes the history ofpopulation flow process and the basic reason, found that the flow of the populationwill inevitably lead to the changes of the local ethnic minorities traditional farmingmethods, on the theory of environmental economics and sustainable development, tothe number of cultivated land resources caused by farming methods, quality ofreduction, explore the population flow influence on cultivated land resource security,finally, puts forward relevant policy Suggestions for the sustainable development ofcultivated land resources. Hope that through the analysis of the affecting factors ofcultivated land resource security, provide a reference for the perfection of cultivatedland protection mechanism.
