The Ecological Recovery Of Abandoned Lands Of Mines Landscape Evaluation Research

Due to the development of social construction, in order to solve the problem of contradiction between human and land, so the new landscape renovation design of abandoned lands of mines operating, but the effect of the landscape design, especially the ecological restoration and landscape aesthetics does not measure the effect of the standards and methods. In this article, therefore, refer to relevant research data at home and abroad, and the reference of relevant landscape design and the theory of landscape ecology, the selection of evaluation of landscape quality assessment content and the specific evaluation index, attempts to put forward a feasible evaluation method.Based on AHP, on the basis of analytic hierarchy process (ahp), building from macro to micro comprehensive evaluation system suitable for landscape of abandoned lands of mines, a clear evaluation method, establishment of evaluation index weight. The comprehensive evaluation of a problem, should be in after the design of the recovery in what way to restore to achieve recovery has scientific guiding significance.In restorative landscapes of abandoned lands of mines is established after the comprehensive evaluation system, in order to verify its feasibility, the author of Fushun west open pit restorative landscape evaluation practice. In Fushun west open pit shall be carried out in accordance with the contents and methods of the evaluation system of evaluation, its landscape quality evaluation of the comprehensive score of 4.399 points, the overall level of general deviation; Among them, the landscape pattern characteristics of evaluation score of 3.186 points; Community characteristic evaluation score of 6.611 points; Landscape aesthetic quality evaluation score of 3.233 points. After the evaluation results for specific analysis, aiming at the problems in the landscape design is put forward specific ideas and design guidance, paper’s main conclusions are as follows:First, on the landscape evaluation of Fushun west open pit, the overall level of landscape general deviation. Through to evaluate the landscape pattern of Fushun west open pit, the result is bad, and every part of the score is not high. Explain the characteristics of the landscape pattern in there exist many problems, and have certain irrationality in the landscape design. Evaluate the community structure characteristics of Fushun west open pit, the vast majority of numerical and good at, that the landscape of the community recovery pattern has achieved certain success, also found in the evaluation, while the community structure characteristics of the recovered has obtained the certain effect, but there are still species and community structure of a single problem, should be in the design of the recovery after improved. The landscape aesthetic quality evaluation of Fushun west open pit, can draw landscape aesthetic quality result for the general evaluation area. Through the analysis of the specific evaluation factors, can be concluded that landscape relatively good performance in terms of integrity, the score is higher, low score in terms of diversity evaluation level for the poor. Thus evaluation area landscape elements is relatively drab, less participatory activities, should be a detailed design.Second, through to the practice of the evaluation theory, the evaluation system of certain significance to judge, be practical, the evaluation result can be in a certain extent response evaluation area, especially in ecological restoration of mining landscape effect and landscape effect. In wait for the evaluation results at the same time, can also according to the problems, put forward the constructive opinion and the specific design, the late maintenance.Third, although the although there are certain adaptability evaluation system, but there still exist some shortcomings. Indicators for evaluation index data, some data is not easy to get, it’s more difficult to evaluate. In addition, some data index between the definition of fuzzy, may cause a certain repeated in the evaluation, makes the accuracy of the evaluation results are limited. In to get in the way of evaluation standards, because we have no a unified standard, so its for a standard selection can only rely on predecessors’research contents in the judgement and expert experience, has certain limitations, so hope to establish the corresponding database specification is made to the evaluation criteria, is conducive to the follow-up work. And because the landscape restoration is a long-term process, the sustainability of ecological operation is not possible through one-time measurement results, should carry on the long-term monitoring.
