Abstract:Landsenses ecology is able to help planning builders to understand public feelings, ideas and opinions, to integrate perception data into the planning process, and to fully reflect peoples' vision for a good ecological environment, without reducing artistry and scientificity of the planning and design, in order to provide support for the harmonious coexistence of nature and human beings. Through the effective combination with ecosystem services and sustainable development, the connotation and extension of landsenses ecology have been expanded, while the concepts of landsenses creation and landsenses evaluation have been further clarified. Landsenses evaluation means evaluating and predicting the present situation or construction process of certain landsenses based on particular purpose and corresponding evaluation criteria. Thus, landsenses evaluation can provide a scientific basis for understanding, establishing and improving landsenses, as well as for ecological planning and construction based on landsenses ecology. In addition to following some principles and objectives of general landsenses ecology, the main theoretical basis of landsenses evaluation originates from theories of ecosystem service, sustainable development, complex ecosystem, and ecological civilization. The principles of landsenses evaluation mainly include harmony and sustainability of landsenses, and systematicness and pertinence of evaluation. The specific methods of landsenses evaluation can be divided into single factor evaluation based on certain evaluation objectives and comprehensive evaluation considering multiple factors. The former is generally limited to specific evaluation objectives or considering restrictive factors, while the latter contains the analytic hierarchy process, the data envelopment analysis, and the importance- performance analysis. Within their application scope, each evaluation method has its own advantages and disadvantages. Different methods should be flexibly used in landsenses evaluation according to diverse situations and purposes. It is also necessary to fully consider not only the unity of human perception or vision and natural elements, but also the unity of landsenses creation, ecosystem services and sustainable development awareness. The research and application of landsenses evaluation are at the initial stage, and there are a number of difficulties and problems in its development process, such as the intersections of different disciplines, the construction of indicator systems, the trend assessment rather than accurate expression, the complex scale issues, the particular technical methods, and so on, which should be focused to study in the future. With the intersection and integration of relative disciplines, the progress and development of technology, and the joint efforts of relevant scholars, landsenses evaluation will effectively guide human beings to make rational use and scientific management of natural resources.
