【摘要】：土地乃财富之母,是承载农业园区内一切生产经营活动的载体。经过近三十年的快速发展,农业园区在具体建设和运营过程中,暴露出一些问题,其中持续发展的需要和土地有限供给的矛盾尤其突出,在资源禀赋、生产水平、生态环境、人力资源均不占优势的丘陵山区,现代农业生产发展的任务尤为艰巨。基于当前形势,农业园区健康持续发展必须考虑土地资源合理利用和管理。因此,进行农业园区土地集约利用的理论和实证研究,对农村资源、社会、经济和生态可持续发展具有重要意义。本文以可持续发展理论、区位理论、地租理论和土地规模报酬理论为基础,采用文献研究、实际调查、定性与定量相结合的方法,系统梳理了现代农业园区和土地集约的理论与方法；然后以蓬溪县农业园区为例,建立农业园区土地集约利用评价指标体系,并借助BP-神经网络模型开展定量评价研究；在理论和实证的基础上基于综合分析结论,得出了提高现代农业园区土地利用集约度的对策建议。第一,界定了农业园区土地集约利用内涵。研究定义农业园区土地集约利用是土地利用结构的合理化,是空间布局与数量的优化；是农业生产用地的规模化,通过产业的集聚发挥较大辐射和示范效应；是土地利用的充分化,最大限度地降低撂荒地数量；是土地产出的高效化,最终实现经济、社会和生态效益的统第二,构建了农业园区土地集约利用评价模型对农业园区进行了实证研究。本研究从农业园区土地利用现状、土地利用效益和管理绩效三个方面,分别选取了23个具体指标,构建了基于BP-神经网络的现代农业园区土地集约利用评价模型进行实证研究,计算出2011-2015年蓬溪现代农业园区土地利用集约度分别为：0.3921、0.5152、0.5331、0.5627、0.6320,研究结果表明：蓬溪现代农业园区自建设以来,区域内土地的产出效益与利用率已达到初步集约的水平,且增长态势较为稳健,但仍有值得改进和提高之处。第三,对策建议。流转报征两手齐抓,做大土地利用增量；强化土地总规地位,确保规划执行力度；增强节约集约观念,提高土地利用效率；科学谋划产业布局,增强示范带动能力；加强生态保护意识,确保土地永续利用。
[Abstract]:Land is the mother of wealth. It is the carrier of all production and management activities in the agricultural park. After nearly thirty years of rapid development, the agricultural park has exposed some problems in the process of construction and operation. The contradiction between the needs of sustainable development and the limited supply of land is especially prominent, in resource endowment, production level, ecological environment, and people. The task of the development of modern agricultural production is particularly arduous. Based on the current situation, the rational utilization and management of land resources must be taken into consideration for the sustainable development of the agricultural park. Therefore, the theoretical and empirical research on the intensive use of land in the agricultural park is carried out, and the sustainable development of rural resources, society, economy and ecology will be carried out. In this paper, based on the theory of sustainable development, location theory, land rent theory and land scale reward theory, the theory and method of modern agricultural park and land intensive are systematically combed with the method of literature research, actual investigation, qualitative and quantitative combination, and the agriculture park of Pengxi county is taken as an example to establish agriculture. The evaluation index system of the land intensive utilization of the park and the quantitative evaluation research with the BP- neural network model are carried out. Based on the theoretical and empirical analysis, the countermeasures and suggestions for improving the intensive degree of land use in modern agricultural parks are obtained. First, the intension of intensive land use in the agricultural park is defined. The intensive use of land is the rationalization of the land use structure, the optimization of the spatial distribution and quantity, the scale of the land for agricultural production, the greater radiation and demonstration effect through the agglomeration of the industry, the charge and differentiation of land use, the maximum reduction of the number of abandoned land, the efficiency of the land output, and the final realization of the economy, and the society. The land intensive use evaluation model of the agricultural park was constructed for the agricultural park. This study selected 23 specific indexes from three aspects of the land use status, land use efficiency and management performance of the agricultural park, and constructed the modern agricultural park land based on BP- neural network, which was based on the BP- neural network. The intensive use evaluation model is used to carry out an empirical study. The land use intensivism of Pengxi modern agricultural park in 2011-2015 years is calculated as: 0.3921,0.5152,0.5331,0.5627,0.6320. The results show that since the construction of Pengxi modern agricultural park, the output efficiency and utilization rate of land in the region has reached a preliminary intensive level and increased. The situation is more robust, but still worthy of improvement and improvement. Third, countermeasures and suggestions. The circulation of two hands should be carried out to improve the land use increment, strengthen the status of the land general regulation, ensure the implementation of the plan, strengthen the concept of economical and intensive, improve the efficiency of land use, scientifically plan industrial layout, enhance demonstration and drive capacity; strengthen ecological protection. Protect the consciousness and ensure the sustainable use of the land.
