alternatively people control
Balance of the ecological balance in the ecosystem structure and feature within a decisive time, the comparative stability of the state, its matter and energy input and output close to equal, the external interference through self-regulation (alternatively human control) behind to the aboriginal stability state. When the outer sedition of ecosystems beyond the aptitude of self-control can not be restored to the original state that the ecological balance of the ecological imbalance alternatively abuse. ecological balance is dynamic. maintaining the ecological balance is not fair to maintain its original stable state. ecological system can under the influence of anthropogenic salutary to establish a current balance to accomplish a more reasonable structure, more effective and better eco-efficiency functions. The upon definition shows:
(1) the normal ecological system namely the long-term from the easy apt the complicated succession Finally, manner a relatively settled state, the evolution of this point, the type and quantity of category remained relatively stable; energy input and output approximately equal apt that system of stamina stream and nutrient cycling can be a long period to preserve poise. At this point,toronto asian escort, the system creatures will must fill all accessible space, environmental resources can be the most reasonable and efficacious use. For sample, tropical rain jungle is a mature stage of development to the community, and its obvious perpendicular stratification, complicated architecture, per unit area in multi-species, each occupies a rewarding environmental conditions, coordination with every other to live attach, their productivity is also tall;
(2) ecosystem has a certain ability to regulate the interior ();
(3) the ecological balance is dynamic. in the process of biological mutation and community succession is involved in the balance continues to crash the old, the process of establishing a new balance. human nature should be inspiration, do not look by the negative ecological balance, but to take the initiative to maintain the ecological balance for human needs (such as the establishment of nature reserves), or do not encounter their requirements to break the antique balance,3 Luliang Kong, new balance (such as the abandon is became into one oasis), the ecological system reasonable structure, function better and more effective.
ecological balance within the ecosystem is the stability of the two aspects: 1 is the biological species (ie, biology, plants, microorganisms) and quantity of the combination is relatively stable; other On the one hand non-biological surroundings (including atmosphere, sunlight,toronto escort, water, soil, etc.) remain relatively stable. ecological balance is a dynamic balance. For example, replacement of individual organisms will proceed to happen, merely the entire system remains stable, not dramatic changes in biomass .
balance of the ecosystem, once lost, the chain will occur quite solemn consequences. For example, fifty years, China has fired the sparrow as the few years, there was a serious pests, agricultural production was a great detriment.
Scientists later discovered that sparrows dine insects athletes. eradicated the sparrow, the natural enemies of pests is not to wantonly multiply, guiding to pests occur, a sequence of tragic consequences of agricultural crops. the balance of the ecosystem of nature is constantly afterward a long time to set up a dynamic equilibrium. Once damaged, some balance can not be rebuilt, negate consequences may be the human efforts can not repay. So if human absence to adore the ecological balance, and aid maintain this balance, meantime not cozy to break it.
Other Definition: refers to the natural ecosystems of biological and environment, the interaction between biological and bio- The dynamic equilibrium established contact.
also understood as the water, soil, air, temperature, consisting of non-living components. Each makeup is not isolated, but interrelated and mutually conditioned unified complex. by the interaction between them to achieve a relatively stable equilibrium, known for the ecological balance. in truth it is in the ecosystem production, consumption, decomposition to maintain stability between. If one makeup of which is also drastically changed, a necklace response can occur, so that the dispose of ecological balance . If a chemical material or a chemical factor too much more than the customary content of the natural state, will also affect the ecological balance. ecological balance to maintain normal growth and development of biological, the fundamental condition for procreation, but also the basic conditions for human survival .
