Abstract

Abstract: Taking Nanlv land consolidation project in Tunchang County of Hainan Province as an example, the authors explored the method based on analysis of landscape pattern and restrictive factors. Firstly, the landscape pattern of landscape scale and type scale is analyzed by ArcGIS and FRAGSTAS. Then, using the units of agricultural land classification as the unit of analysis, the restrictive factors are analyzed by the method of combination of grading factors. The combination types of grading factors and their restrictive degree of each unit is gotten. Lastly, based on the result of analysis of landscape pattern and restrictive factors, planning and design modes of land consolidation are proposed. Among them, the spatial layout planning is to determine the pattern of land use of the land consolidation project, including the spatial location and quantity ratio, and the position of the land consolidation project. The ecological design of land consolidation is to design the land types and land consolidation project based on ecological protection, including the plots, field roads, the irrigation canals and ditches. The research can provide a scientific basis for the planning and design modes of land consolidation in tropical plateau area.

Key words: land consolidation, landscape pattern, restrictive factors, planning and design

摘要： 以典型热带台地地区的海南省屯昌县南吕镇土地整治项目区为例, 探讨基于景观格局与限制性因素分析的土地整治规划设计技术。首先, 利用ArcGIS 和FRAGSTAS 软件, 计算项目区景观尺度和斑块尺度的景观格局指数, 分析项目区的景观格局情况; 然后, 采用农用地分等因素组合的方法, 分析项目区耕地利用的限制性, 以项目区农用地分等单元为基本评价单元, 分析评价单元的分等因素组合类型以及不同组合类型对农用地质量的限制强度, 以此明确评价单元整治的难易程度和整治重点; 最后, 在对项目区进行景观格局与限制性因素分析的基础上, 进行项目区的规划设计, 包括空间布局和生态设计两部分, 空间布局主要是确定整治项目区土地利用格局, 包括确定各类用地的空间位置和数量比例关系以及各种地类及整治工程的位置, 生态设计是对项目区内的用地类型和整治工程进行生态化设计, 包括对田块、道路、沟渠等提出适合热带台地地区气候和地貌特点的生态化措施。研究结果可为热带台地地区土地整治规划设计的实践工作提供科学依据。
