Study On Development Of Urban Agriculture Sustainable Land Use In Wuhan

Urban agriculture as an aspect of sustainable development, it’s sustainable development is directly related to the overall sustainable development strategy whether can be smoothly achieved. And sustainable use of land is the premise for the sustainable development of urban agriculture. Therefore, the relevant study on the urban agriculture sustainable land use is very necessary.With the everlasting improvement of the urbanization and population explosion, the contradiction between the infinite land demand and limited land resource is increasingly acute, which led to ecological environment deterioration, soil fertility levels descend, and many other problems. Therefore, In order to ensure the implementation of sustainable development strategy,we need evaluate the sustainable land use level of urban agriculture and put forward for the construction of "Two-oriented society" to promote urban sustainable utilization of agricultural land.This paper takes Wuhan as the studying area,analyzing the natural、social and economic conditions and present condition of the land use and existing problems.In the perspective of sustainable, follow the principle of index selection, according to the evaluation purpose,from the ecological,economic and social sustainable three aspects,this thesis establishes the comprehensive evaluation system of the sustainable land use from three aspects-sustability of ecology,economic and society, and gives my own viewsResearch results show that:(1) From 2006 to 2013, land ecological sustainability, economic sustainability and social sustainability and the comprehensive level of urban agricultural land use level of Wuhan are all in the increasing stage;Variations in economic sustainability is the largest, before 2008,economic sustainability is the lowest level of all,after this, it has been greatly increased; Ecological sustainability’s change is the lowest,and ecological sustainability is always in a leading level basically.Since 2008, Social sustainable utilization level has been lower than other three sustainable utilization level;(2) The mainly sustainable utilization obstacle factors are as follows:ecological sustainability includes land reclamation rate, per capita arable land,fertilizer use intensity index;Economic sustainability includes agricultural GDP per capita,comprehensive agricultural mechanization level indicator; Social sustainability includes rural residents engel’s coefficient, annual per capita net income of farmers, urban and rural income ratio and other indicators. Obstacle factors for sustainable use of land, appearing every year, are land reclamation rate, annual per capita net income of farmers, urban and rural income ratio, the strength of fertilizer use, rural residents engel’s coefficient;The trend of Obstacle factors development:the per capita annual net income of farmers shows a tendency of decrease year by year; Land reclamation rate, urban and rural income ratio, fertilizer use intensity, per capita arable land area shows a tendency of increase year by year.According to the empirical study,we know the level of urban agriculture sustainable land use, and find the obstacle factors, in order to improve the level of urban sustainable utilization of agricultural land, we combine with the practical situation of Wuhan,and put forward a few Suggestions:(1)To establish scientific and effective planning of wuhan urban agriculture land use; (2)Improving ecological environment of urban agriculture land use; (3)To adjust urban agriculture land use structure, optimize the agricultural industrial layout; (4)Improving urban agriculture land use system of laws and regulations, establish and perfect the system of land use; (5) To reduce the gap between urban and rural areas, promoting rapid economic development in urban agriculture; (6) We will deepen the reform of the land use system and implement land scale management; (7) Safeguard the quantity of cultivated land, improve the quality of cultivated land.
