【摘要】：都市农业作为可持续发展的一个方面,其能否可持续直接关系到整体可持续发展战略能否顺利实施。而土地的可持续利用是都市农业可持续发展的前提。因此,对都市农业土地可持续利用进行相关研究显得十分有必要。随着城市化率的不断提高,人口急剧膨胀,无限的用地需求与有限的土地资源之间的矛盾愈发尖锐,由此引发了一系列的生态环境恶化、地力水平下降等诸多问题。为了保证可持续发展战略的顺利实施,就需要对都市农业土地可持续利用水平进行测评并提出促进都市农业土地可持续利用的政策建议,为“两型社会”保驾护航。本文以武汉市为研究区域,分析了武汉市的自然、社会经济状况与土地利用现状及存在的问题,以可持续为视角,遵循指标选取的原则,依照评价目的,从生态、经济、社会的可持续性三个方面,建立了综合评价指标体系,对都市农业土地可持续利用水平进行了研究,并给出自己的看法和意见。研究结果表明：(1)2006至2013年,武汉市都市农业土地生态可持续性、经济可持续性、社会可持续性和综合可持续利用水平均处于递增的阶段；经济可持续性变化幅度最大,2008年以前,经济可持续性水平最低,在这以后,一直处于快速增长的阶段：生态可持续性变化幅度最小,并基本上处于领先水平。社会可持续利用水平自2008年以后,一直低于其它三项可持续利用水平；(2)可持续利用障碍因子主要分布：生态可持续方面为土地垦殖率、人均耕地面积、化肥使用强度等指标；经济可持续性方面为人均农业GDP、农业机械化综合水平等指标；社会可持续性方面为农村居民恩格尔系数、农民年人均纯收入、城乡收入比等指标。历年都会出现的可持续利用障碍因素有土地垦殖率、农民年人均纯收入、城乡收入比、化肥使用强度、农村居民恩格尔系数五个指标；障碍因子发展态势：农民人均年纯收入呈现出逐年减少的态势；土地垦殖率、城乡收入比、化肥使用强度、人均耕地面积呈现出逐年增加的态势。根据实证研究本文了解了都市农业土地可持续利用水平,并找到了阻碍可持续利用的因子,为了改善都市农业土地可持续利用水平,本文结合武汉区域实际情况,提出几条建议：(1)制定科学有效的武汉都市农业土地利用规划；(2)改善都市农业土地利用生态环境；(3)调整都市农业土地利用结构,优化农业产业布局；(4)完善都市农业土地利用法律法规体系,建立健全土地使用制度；(5)缩小城乡差距,带动都市农业地区经济快速发展：(6)深化土地使用制度改革,实行土地规模化经营；(7)保障耕地数量,提高耕地质量。
[Abstract]:As an aspect of sustainable development, the sustainability of urban agriculture is directly related to the smooth implementation of the overall sustainable development strategy. The sustainable use of land is the premise of sustainable development of urban agriculture. Therefore, it is very necessary to study the sustainable use of urban agricultural land. With the increasing of urbanization rate and the rapid expansion of population, the contradiction between infinite land demand and limited land resources becomes more and more acute, which leads to a series of problems such as deterioration of ecological environment, decline of soil capacity and so on. In order to ensure the smooth implementation of the sustainable development strategy, it is necessary to evaluate the level of sustainable use of urban agricultural land and put forward some policy suggestions to promote the sustainable use of urban agricultural land in order to protect the "two-type society". Taking Wuhan as the research area, this paper analyzes the natural, social and economic situation, the present situation of land use and the existing problems in Wuhan City. From the perspective of sustainability, following the principle of index selection, according to the purpose of evaluation, from the perspective of ecology and economy, In the three aspects of social sustainability, a comprehensive evaluation index system was established, and the level of sustainable use of urban agricultural land was studied, and its own views and opinions were given. The results show that: (1) from 2006 to 2013, the ecological sustainability, economic sustainability, social sustainability and comprehensive sustainable use of urban agricultural land in Wuhan are in an increasing stage; Economic sustainability has changed the most, with the lowest level of economic sustainability before 2008, and has since been in a period of rapid growth: the smallest change in ecological sustainability and basically a leading level. The level of social sustainable use has been lower than the other three levels of sustainable use since 2008; (2) the main distribution of obstacle factors of sustainable use is as follows: land reclamation rate, per capita arable land area, chemical fertilizer use intensity and so on, economic sustainability is the comprehensive level of agricultural GDP, agricultural mechanization per capita, and so on. In terms of social sustainability, Engel's coefficient of rural residents, per capita net income of farmers, urban-rural income ratio and other indicators. The obstacles to sustainable use in the past years include land reclamation rate, annual per capita net income of farmers, income ratio between urban and rural areas, intensity of fertilizer use, and Engel coefficient of rural residents. The development trend of obstacle factors: the per capita net income of farmers is decreasing year by year; the rate of land reclamation, the income ratio between urban and rural areas, the intensity of fertilizer use, and the per capita cultivated land area are increasing year by year. According to the empirical research, this paper understands the sustainable use level of urban agricultural land, and finds out the factors that hinder the sustainable use. In order to improve the sustainable use level of urban agricultural land, this paper combines the actual situation of Wuhan region. Some suggestions are put forward as follows: (1) to formulate a scientific and effective land use plan for urban agriculture in Wuhan; (2) to improve the ecological environment of urban agricultural land use; (3) to adjust the structure of urban agricultural land use and optimize the layout of agricultural industry; (4) to perfect the laws and regulations of urban agricultural land use and to establish and perfect the land use system; (5) narrowing the gap between urban and rural areas to promote the rapid economic development of urban agricultural areas: (6) deepening the reform of land use system and carrying out large-scale land management; (7) ensuring the quantity of cultivated land and improving the quality of cultivated land.
