Embodiment 1

[0046] Embodiment 1, the evaluation of Shenzhen mangrove health status and artificial restoration effect

[0047] All the data in this embodiment are represented by relative values, that is, the measured data is compared with the data in the positive control area, and the obtained value is the final relative value. Expressed in relative values, the influence of seasonal conditions on experimental data can be eliminated.

[0048] 1. Build an evaluation model

[0049] 1. Determination of the evaluation index system

[0050] Since health evaluation indicators involve multiple disciplines and there are many types of indicators, it is necessary to screen out factors that are consistent with plant health connotations and evaluation goals from complex information. Therefore, it is necessary to first establish the screening principles of evaluation indicators. The construction and screening of indicators should focus on the following objectives: (1) belong to the industry-recognized...

Abstract

The invention discloses a method for evaluating the health condition and human-induced restoration effect of mangrove forest and application thereof. According to the method, mangrove forest which is polluted on coastal wetland in Shenzhen City and is under restoration is taken as a research implementation object, and data of three different mangrove types, namely, aegiceras corniculatum, kenaelia candel and sonneratia apetala in a negative control region, a restoration region and a positive control region in August (summer) and November (winter) of 2014 is acquired respectively for analysis. As proved by the result, a mangrove forest health index selected with the method, and a health index computed according to a set index weight and an establish health evaluation system are consistent with the preferential order of the health state of the mangrove forest. The method is suitable for the health evaluation of manually-restored mangrove forest on coastal wetland in Shenzhen City, and can be adopted in other regions as a method for evaluating the human-induced restoration effect of the mangrove forest.

Description

technical field [0001] The invention relates to a method for evaluating mangrove health status and artificial restoration effect in the field of ecology and its application. Background technique [0002] Plant health assessment is an important field of ecological research, and it is also one of the frontiers of ecology today. As the intensity of human disturbance to ecosystems continues to increase, people's understanding of ecosystem service functions gradually deepens, and the requirements for ecological environment quality continue to increase, the health of ecosystems has received more and more attention. Plant health assessment is an important means of ecosystem cognition and the basis of ecosystem management. In recent years, plant health evaluation has become a research hotspot at home and abroad. [0003] According to the ecosystem health assessment method, the plant health assessment also adopts two methods of indicator species method and index system method (Yang...
