- Abstract:
- Based on river health assessment, focusing on several urgent issues of river ecological health and river improvement, offering scientific explanations and proofs on river health and weak reaches of it, this research summed up assessment methods and various indices at home and abroad, striking up fuzzy matrix assessment to measure the river health, which was in view of fuzzy relation combining principle, to comprehensively judge the condition of the river membership hierarchy in various factors. There were target layer, criterion layer and index layer specially in this assessment, which was adopted fuzzy matrix to calculate statics layer upon layer. At last, it was divided into four broad headings named: natural, near natural, degenerate, artificial. The assessment result showed that the status of the Huaisha River was 2.6 (natural: 41%, near natural: 32%, degenerate: 27%). Subsection assessment results indicated that: Sancha Reach, Bohai Reach, Koutou Reach were in good condition, Siduhe Reach, Nanye Reach, Xinying Reach were needed to adopt reasonable measurements to improve river ecosystem. The assessment put forward the reasonable suggestions and improvement measures which can offer several ideas to the health in suburban river and the sustainability of the eco-environmental construction.
