| With the advance of a series of policies about urbanization process, overall development of urban and rural development, new urbanization, the construction of beautiful countryside, the rural areas as an important type of social space, influenced by nature, politics, economy, culture,and the landscape pattern has been in a dynamic change process. In order to meet the needs of rural landscape ecological security and sustainable development, in this paper, an indepth study on the selection and optimization strategy of rural development mode based on the rural landscape pattern dynamic changes, deepen the process of "current situation-cause analysis- simulation prediction-optimization strategy ",enrich the theoretical system of rural development planning, so it has certain theoretical significance. Through the analysis of the characteristics of landscape pattern, function evaluation and development pattern of 11 towns in the planning area of Lu'an City, put forward the optimization strategy and control method based on the stable and sustainable development goal of landscape pattern in rural area, this is a reference to the rural landscape pattern optimization policy formulation and rural construction planning in the Central City suburb, also has certain practical significance.On the basis of summarizing the research progress of rural landscape pattern, combined with the theory of landscape ecology, Using the 3S, Fragstat, CA- Makov technical means to study landscape evolution characteristics and summarize the characteristics and rules of the study area in 2005-2015. To explore the driving factors of landscape pattern change, and simulate the status of landscape pattern in 2025, to explore the driving factors of landscape pattern change, and simulate the status of landscape pattern in 2025, finally, put forward the optimization strategy and pattern choice of rural development mode based on landscape landscape function evaluation.(1) Based on the remote sensing image data interpretation of of the township of Lu'an city planning area in 2005/2015, the landscape pattern evolution characteristics and the law of the study area were analyzed, and the landscape index was used as reference to analyze and summarize the current situation of landscape pattern in 2015. The research results show that: on the regional scale, landscape pattern is in the process of dynamic change Different landscape types in spatial distribution are staggered and scattered, the degree of landscape fragmentation is higher and the shape of the patch is irregular.(2) Through analysis correlation between construction land, agricultural land and influence factors,and draws the conclusion: building landscape and farmland landscape change and land suitable, demographic changes, changes in economic factors showed a positive correlation, and and traffic location presented negative correlation, the correlation of town level is not obvious.(3) Application CA-Makov model to simulate the landscape pattern of Lu'an urban planning area in 2025,Construct the landscape type and probability transfer matrix, and analyze the evolution trend of the future in quantity and space. The results showed that: It is expected that in 2025 the total construction land landscape continued to grow, the growth rate of agricultural land landscape has slowed, and the slow decrease of forest landscape and historical development in the opposite direction, and the water landscape remained stable. The landscape pattern of each township showed different trends, but the overall development trend and regional similarity.(4) Put forward rural development mode based on the evaluation system of rural landscape function: the type of suburban service, industry Oriente, characteristic resource, tourism resource, agricultural sightseeing, agricultural cooperative. Taking all the villages of 11 towns in the study area as an example, choose different development mode, and put forward the optimization strategy. |
