Abstract

Sustainable development requires to maintain a certain amount of resource owners, in particular, is closely related to the amount of arable land resources and human survival. China, as a developing country, is in the process of industrialization, rapid urbanization period of arable land into non-agricultural land faster and more severe land degradation, the relationship between people and land is relatively tight, in this context, China has put forward the sustainable use of land strategy. To achieve sustainable land use (mainly refers to the sustainable use of agricultural land resources), development of agricultural land resources is an important way. Additional land, improve land productivity and economic efficiency, protect the natural landscape and improve the ecological environment, the development of agricultural land resources to achieve sustainable land use, thus achieving sustainable agriculture and rural development. Evaluation of agricultural land resources development contribution to the sustainable use of land is selected as the strategic objectives of agricultural land development, feasibility analysis basis. In this paper, from the method (Chapter II) and empirical (Chapter III) contribution to agricultural land resources development in Jiangsu Province, the sustainable use of land evaluation. Evaluation method using sub-criteria hierarchical index group evaluation to select representative indicators under the five criteria for sustainable land use evaluation, and selection of econometric methods (by Solow incremental model contribution rate), and interrupted time series ( land use agricultural land development intervention before and after comparison), the same amount of non-groups design method (the project area and the non-project area comparison) methods to evaluate the contribution to the sustainable use of agricultural land resources development on land. And that the area of ??the different regions and different levels, is not the same as the order of importance of the selected evaluation indicators and indicators for the evaluation of this article, the evaluation of the specific design on three different levels in the the provincial project area level and plots level indicators. The results of the evaluation are: complements a lot of land for nearly a decade, Jiangsu Province, agricultural land development, additional land arable land accounts for 45.6% of reduction eased farmland downward trend; improve the productivity of arable land, fold grain production accounts for increased development of agricultural land annually fold grain yield of 0.52% -4.67%, while the development of agricultural land also enhanced production stability; made an important contribution to the growth of agricultural production, agricultural output, promote regional economic development, the annual increase in the value of agricultural production through the development of agricultural land approximately 6.4 billion by the model, production increased by 24% and 32% of the output growth can be attributed to the development of agricultural land; development per person per year for the province increased 4.17 kg of grain to ensure food security; development of agricultural land also increased farmers' income improve the regional balance; improved the ecological environment and promote the modernization of agriculture, made a large contribution to the sustainable use of the province's land. The summary of the mode can provide reference for agricultural land development project planning, design. Chapter Jiangsu Province agricultural land resources development mode on the basis of the investigation analysis, summary and analysis of the Huaibei Plain mainly low-yielding farmland farmland remediation mode; Lixiahe low-lying land transformation and lakes swing comprehensive development mode; hilly area of ??three-dimensional mode of development in small watersheds; the coastal beach development model; wasteland reclamation mode. And summarizes the plains farmland remediation, development of hills and mountains, beach development of different investment business model. System construction is a guarantee for the success of the development of agricultural land, this paper analyzes the construction of the system in the development of arable and non-arable land, it is recommended that the implementation of the stock cooperative system in the development of agricultural land, especially non-arable land development. Under the new situation the focus of the development of the agricultural land has been changed, and focuses on the improvement of the ecological environment, improve land quality, improve the regional balance. Development of public welfare, size, and other requirements of the government to play an active role in the development of the agricultural land, and strengthen planning and management induction system, improve infrastructure, services comprehensive.
