Modern Agricultural Park Landscape Pattern Around The Planning

In recent years, the majority of China’s rural areas are in the transformation process from the traditional agriculture landscape to modern agriculture landscape. However, when extensive use of fertilizers, pesticides, herbicides and modern agricultural engineering facilities makes land use and land cover change in the way, the ecological and aesthetic benefits of agricultural landscapes suffered serious damage. Therefore, an urgent need that landscape pattern optimizing and landscape heterogeneity increasing can increase the ecological restoration ability may achieve sustainable development in agricultural landscapes.This study following the theories and methods of landscape ecology, The main contents and results are as follows:The first chapter is an introduction. This paper first discusses the research background, followed by the park of cases’s profile, including the analysis of natural, economic and social conditions pre-planning and after planning, then the purpose and significance of this research,finally, five kinds of research methods and technology roadmap.The second chapter is the research progress of landscape pattern. The main reviews landscape categories, landscape pattern, landscape ecological security evaluation and optimization of landscape pattern dynamics studies on the domestic.The third chapter is Huaibei Gaoyue modern agricultural demonstration zone landscape pattern change analysis. Mainly maps of existing in 2012 and 2018 as the base data, combined with local planning documents, field investigation, the pre-processing industry to extract the relevant information needed, and in the case of the park divided into two kinds of landscape classes,6 Landscape subclasses and 10 landscape units, and draw out two different periods in the case of the park landscape distribution. At the same time with landscape index as the study index, separately from plaque type and landscape level to study, described landscape spatial pattern characteristic in the case of the park, and were compared with analysis of spatial and temporal patterns.The fourth chapter is Huaibei Gaoyue modern agricultural demonstration zone of landscape ecological security evaluation and analysis. From the perspective of ecological security to use the mathematical models law, were selected index of landscape structure and indicators of landscape ecosystem services built landscape ecological security evaluation system, evaluation results show that pre-planning in 2012 and after planning in 2018 landscape ecological security evaluation index were 59.534%,80.364%, landscape ecological security level from i rising to iii, etc., landscape ecological security from the "General" up to "excellent" level. Meanwhile reveal cases park landscape structure and spatial layout problem.The fifth chapter is Huaibei Gaoyue modern agricultural demonstration zone optimization strategy of landscape pattern. There are still some problems for landscape pattern after the planning of the park, in premise of compliance with the overall ecological function optimization, multi- objective, optimization, scale appropriate, balanced selection of six basic principles of landscape pattern optimization, put forward to strengthen the ecological corridor construction, building large patches of natural vegetation, increasing landscape diversity of three kinds of landscape pattern optimization measures, five landscape ecological management strategies and five landscape ecological protection measures.The sixth chapter is the conclusion and discussion. The main conclusions is to use the geographic information system technology landscape pattern to analysis and compare the level of plaque type and landscape type level of the index before and after Huaibei Gaoyue modern agricultural demonstration zone in 2012 and 2018; and build landscape ecology safety evaluation system to evaluate the landscape ecological security around the planning, and then raised the issue of landscape pattern; on the basis of better ecological security for further optimization to the planning area, proposed three optimization measures, also proposed the landscape ecological management and landscape ecological protection to modern agriculture park. Landscape pattern in modern agricultural park, the landscape pattern optimization still inadequate.
