Abstract: |
The key to implement the ecological protection policy is to
evaluate and make clear the important areas of ecological protection.
The evaluation of the importance of ecological protection in the "double
evaluation" guide is mainly aimed at the provincial scale, and lack of
correction and refinement methods at the city and county scale. Taking
Jiangxia District of Wuhan City as an example, this paper studies the
importance evaluation of ecological protection of cities and counties
under the background of national land spatial planning. Based on the
regional characteristics of Jiangxia District, soil and water conservation,
water source conservation, biodiversity maintenance, soil and water loss
sensitivity and waterlogging risk are selected to construct the evaluation
index system. The evaluation method of biodiversity maintenance is
optimized from the "species" dimension, and the waterlogging risk
evaluation method is explored by using InfoWorks ICM hydrodynamic
model. Five indicators are evaluated and synthesized to get the
preliminary judgment results. The preliminary judgment results are
revised in combination with policy based ecological protection lines,
protected areas and important natural elements. The results showed that
the most important area and important area of ecological protection in
Jiangxia District are 565km2
and 220km2
, accounting for 34.2% and
13.3% of the total area of Jiangxia District respectively |
